Abstract :
This paper presents the design and implementation of a 5Gb/s transimpedance amplifier (TIA) with dual shunt-shunt feedback technique to enhance the circuit performance. Measured bandwidth is 4.9GHz and measured transimpedance gain is 60 dB Ω. The chip consumes only 8mW at 1.8V supply voltage and occupies 650 μm × 500 μm in a 0.18 μm CMOS process.
