Current Research

Precision Agriculture Sensing Systems

Precision Agriculture Sensing Systems

Agriculture is one of the main greenhouse emission sources since farm fields emit carbon dioxide, methane and nitrous oxide from fertilizers, cultivation of soils, animal waste and rotting crops. Thus, it is critical to accurately monitor gases to reduce emissions and increase crop productivity. To accomplish greenhouse gas emission sensing system, a low-power embedded readout system with long-range wireless data transmission and machine learning data processing will be developed. The sensing system will enable cost-effective precision agriculture.

Electrochemical Sensor Systems for bio and chemical detection

Electrochemical Sensor Systems for bio and chemical detection

As sensor technology has been developed, electrochemical sensors lead a trend of smart sensing systems, which allows point-of-care-testing. This evolution in the health care area has set a task for researchers to develop new architectures with low power consumption and compactness for the measurement system, as well as achieving accuracy, sensitivity, range and stability. In order to achieve these requirements, ISCS Lab has developed electrochemical sensor readout circuit systems for chemical detection and bio application such as glucose monitoring and gas sensing.

Wearable Health Monitoring Device

Wearable Health Monitoring Device

Wearable health monitoring devices are increasingly being utilized for point-of-care testing (POCT) and disease diagnosis, offering numerous advantages such as real-time data, convenience and the ability to monitor patients continuously outside of traditional healthcare settings, offering the potential to improve patient outcomes. ISCS lab has developed systems to perform gaseous, aqueous and optical phase measurements for human health.

Showcase Projects

Integrated Circuits

Electrochemical Sensing System

Electrochemical Sensing System

The analog front-end circuits for electrochemical sensing is designed to implement various sensing methodologies such as amperometry, conductometry, voltammetry, potentiometry and impedometry.

High Throughput Optical Communication System

High Throughput Optical Communication System

Since high data rates are necessary for optical communication systems, M-ary amplitude shift keying (ASK) has been developed to improve spectral efficiency. The spectral efficiency is measured in terms of bits per second per Hertz (bps/Hz) and is determined by the bandwidth. Thus, M-ary ASK allows higher data rate transmissions at lower bandwidth to carry multiple data bits in a single symbol. In this project, MCML logic is utilized to implement a M-ary ASK transmitter, which consists of an encoder, a D-Flip flop, a signal generator and a laser driver. The differential topology is employed in all circuits to stabilize the current ripple in the power supply and to operate in high-speed.

Low Noise Amplifier with Air-suspended RF MEMS Inductors

Low Noise Amplifier with Air-suspended RF MEMS Inductors

This work presents the development of a CMOS Ultra-wide band differential Low Noise Amplifier with air-suspended MEMS inductors substituting standard planar spiral inductors. Air-suspended MEMS inductors offer higher quality inductance factor and higher self-resonant frequency of operation when compared to monolithic spiral planar inductors. This extends the capabilities of a mixed-signal CMOS process, allowing for a high gain, full-spectrum, 3.1 – 10.6GHz UWB Low Noise Amplifier. This is in collaboration with Dr. JB Lee’s group at UT Dallas.

Ultra-Wideband Wireless

Ultra-Wideband Wireless Communication ICS

In current wireless communication applications, high data rate, low power and low cost are desirable because of the surging demand for enhanced performance, battery life and cost-efficiency of the electronic devices. To satisfy the above requirements, UWB technologies in the 3.1-10.6 GHz band for communication systems with the average power emission restriction of -41.3 dBm/MHz has been adopted. Among different types of UWB systems, the impulse-radio UWB (IR-UWB) has been demonstrated to be low power, low cost and highly immune to multi-path fading, due to its less complicated carrier-free architecture and very low transmitting duty-cycle nature. In this project, CMOS integrated circuits have been developed for UWB communication systems.

Glucose Sensing Readout Circuit

Glucose Sensing Readout Circuit

In amperometric glucose sensors, electrical current is generated as a result of the chemical reaction between glucose molecules and sensor electrodes, and this current is then measured by the readout circuit. The current generated by this reaction is proportional to the concentration of glucose. In order to measure the glucose concentration level accurately, the CMOS readout circuit for amperometric sensors is developed to provide the wide input current range, linear output and low power consumption.

In Situ Sensing System for Biological Toxin in HABs

The increasing occurrence of harmful algal blooms (HABs) in water resources worldwide is alarming the environmental and health authorities because of their potential to release lethal biological toxins, in particular, microcystins (MCs) produced from cyanobacterial HABs. To detect MCs, it is required to develop highly sensitive optical sensors. Our work is focused on the development of the readout circuit for the optical sensors.
