چکیده
This paper proposes a low-noise readout circuit with noise floor of 11 fArms/sq(Hz) and bandwidth 1.3 MHz. The novel electrostatic discharge (ESD) leakage current cancellation stage allows the to detect sub-pA range input. A total trans-impedance gain 160 dB is obtained by preamplification 100 × followed transimpedance amplifier (TIA) 1 Mohm feedback resistive gain. reader designed in 0.18 ?m CMOS process consumes 5.6 mW from 1.8 V supply.

This paper describes a method of extending the signal frequency bandwidth while increasing the stability of a CMOS transimpedance amplifier (TIA). The TIA consists of three inverting amplifiers in a series, and a high-pass filter plus a non-inverting amplifier that are connected to the last two inverting amplifiers stated above in parallel. The TIA is fabricated using a 0.35 μm CMOS process and...
