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 ..
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, flick..
The NCP20 is designed to provide a regulated negative voltage from a single positive voltage that is origin from LDO’s Output. The NCP20 operates from a single 2V to 4.4V Voltage and provides an adjustable output vo..
This discrete-time 3rd order delta-sigma analog-digital converter is supplied by 3.3V, and shows 16bit resolution. The measured effective number of bits(ENOB) is 15bit. The sampling rate is 500kS/s. Digital control block..
