CMOS Implementation of High Gain Resonant Transimpedance Amplifier

H. Hasina, Z. Rukshana Farhath, R. Suresh Kumar


This paper proposes a advanced CMOS technology for the design of high gain resonant Transimpedance amplifier. The proposed approach uses the differential amplifier for designing. The differential amplifier is one of the versatile circuits in the analog circuit design. This circuit uses NMOS and PMOS devices. The N-channel MOSFET is used to form the differential pair and P-channel current mirror load is used. This design improves the gain of the TIA. Low noise and high gain TIA are essential modules for optical sensor based systems. The proposed design is performed using 0.18µm CMOS technology. The TIA has a concentrated gain of 70dBΩ and bandwidth of 3.1GHz. The proposed amplifier design is done by using CADENCE virtuoso editor and simulations are performed by cadence spectre.
