Abstract
This article presents a monolithic light-to-digital
converter (LDC) based on silicon nanowires. The silicon
nanowires are arranged in a configuration, which allows can-
cellation for the offset due to dark leakage current and facil-
itates system-level chopping of the signal chain, including the
nanowires. The readout integrated circuit (ROIC) has an ana-
log front end (AFE) with a resistive-feedback transimpedance
amplifier (TIA) to provide a constant voltage that strongly
biases the nanowires. A
