Digital Control Readout Integrated Circuit(ROIC) For Gas Sensor
Proposed digital control readout integrated circuit (ROIC) for gas sensor can solve size, power consumption, and other problems with proposed system. Negative charge pump can apply wide range of negative voltage to gate of HEMT device. Amplify signal effectively with complementary structure and chopper technique which ..
Trans-impedance Amplifier for Gas Sensor Analog Front-end
Transimpedance Ampllifier(TIA) amplifies current to voltage. Nested chopper technique, Weak Inversion design allow low noise, low offset structure.
There are four blocks in TIA. First, by using chopping technique, flicker noise and dc offset is removed with modulation and demodulation of signal. In this case, the
