description This paper presents an inductor-less low-power low-voltage cross-coupled regulated cascode (LV CC-RGC) transimpedance amplifier (TIA) design topology with a negative resistance in addition to the traditional gm-boosting approach. Combining the above techniques leads to enhanced design flexibility without needing an on-chip inductor and extra power consumption. It is particularly beneficial as well when the capacitance of a large photodiode (PD) is located at the TIA input. The TIA is implemented in <inline-formula> <tex-math notation="LaTeX">$0.35~\mu $ </tex-math></inline-formula>m CMOS technology with a maximum ft of 20 GHz. Experimental results demonstrate a transimpedance gain of 60 dB<inline-formula> <tex-math notation="LaTeX">$\Omega $ </tex-math></inline-formula>, a 3-dB bandwidth of 1.8 GHz, and an average input-referred noise current spectral density of 9.2 pA/<inline-formula> <tex-math notation="LaTeX">$\surd $ </tex-math></inline-formula>Hz. The circuit&#x2019;s power consumption and chip area are 2.2 mW and 0.004 mm2, respectively.
