This letter presents a low-power transimpedance amplifier (TIA) that employs an immittance converter, which provides both a negative input resistance to increase the input pole frequency and a negative inductance to improve the circuit stability. These allow for a significant bandwidth enhancement with low power consumption. Two TIAs, TIA1 with 6 GHz and TIA2 with 8.8 GHz 3 dB bandwidths, were fabricated in a standard 0.13- μm CMOS technology and were designed to operate with a 250 fF… CONTINUE READING
