چکیده
This paper presents the design, implementation and simulation of a high-gain, low-power, low-noise CMOS front-end transimpedance amplifier (TIA) for optical interfacing between a biosensor array and analog neural circuits of biohybrid robot controller along with description of Central Pattern Generator (CPG) design used for Cyberplasm based biomimetic robot controller. The proposed TIA uses an improved capacitive-feedback TIA topology with an active load to avoid the design issue from large onchip resistors and to increase the design flexibility in gain-bandwidth trade-offs, and it accomplishes a 100MΩ transimpedance gain, 1MHz bandwidth, 158fA/rt(Hz) input-referred current noise at sensing frequency, near 0° phase shift, and 1V peak-to-peak output swing. The proposed circuit dissipates 132μW from a 1.8V supply and the circuit is implemented and verified on silicon in a standard 0.18μm CMOS 1P6M technology.
