Abstract :
A new technique using parallel current-based circuits and resistive compensation to realize an inductorless transimpedance amplifier (TIA) with enhanced bandwidth is introduced. An example TIA implemented in 0.13μm 1.2V standard CMOS achieves 3dB bandwidth of 11.2GHz when driven by a large 500fF photodiode capacitance. This design enhances the bandwidth by a factor of 3.86 with less than 0.1dB gain ripple, achieving the highest figure of merit among published 20Gb/s inductorless 0.13μm CMOS designs for short-haul applications.
