Abstract
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
$0.35~\mu $
m CMOS technology with a maximum ft of 20 GHz. Experimental results demonstrate a transimpedance gain of 60 dB
$\Omega $
, a 3-dB bandwidth of 1.8 GHz, and an average input-referred noise current spectral density of 9.2 pA/
$\surd $
Hz. The circuit’s power consumption and chip area are 2.2 mW and 0.004 mm2, respectively.

期刊介绍:
IEEE Access® is a multidisciplinary, open access (OA), applications-oriented, all-electronic archival journal that continuously presents the results of original research or development across all of IEEE''s fields of interest.
IEEE Access will publish articles that are of high interest to readers, original, technically correct, and clearly presented. Supported by author publication charges (APC), its hallmarks are a rapid peer review and publication process with open access to all readers. Unlike IEEE''s traditional Transactions or Journals, reviews are "binary", in that reviewers will either Accept or Reject an article in the form it is submitted in order to achieve rapid turnaround. Especially encouraged are submissions on:
Multidisciplinary topics, or applications-oriented articles and negative results that do not fit within the scope of IEEE''s traditional journals.
Practical articles discussing new experiments or measurement techniques, interesting solutions to engineering.
Development of new or improved fabrication or manufacturing techniques.
Reviews or survey articles of new or evolving fields oriented to assist others in understanding the new area.
