Abstract

We propose a simple linear current-to-voltage converter with variable gain in a 0.6 μm CMOS technology. This converter consists of only four transistors and does not use a feedback circuit, which minimizes the used chip area and avoids stability problems. Together with a monolithically integrated photodiode this circuit forms an easy-to-build optical receiver. The noise theory of the converter is discussed and simulated as well as measured results are shown.
