- Abstract
- This paper presents a current-mode transimpedance amplifier (TIA) implemented in a 65nm CMOS technology, in which the mirrored current-conveyor (MCC) input configuration is proposed to lower the input impedance for wide bandwidth, thereby enabling narrow pulse recovery. Also, a feedforward control-voltage generator is suggested to realize automatic gain-control within a single pulse. Post-layout simulations of the proposed MCC-TIA demonstrate the variable transimpedance gain of 58 similar to 77 dB Omega, a wide dynamic-range of 41.9 dB that accommodates the input currents from 18 mu A(pp) to 2.24 mA(pp), the minimum noise current spectral density of 16.8 pA/sqrt(Hz), the power dissipation of 40 mW, and the core area of 1.0 mm(2).
