    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 mod..
