Abstract

In this paper we present a novel 1V current reference for a transimpedance amplifier (TIA) which provides a small dependence of the output response on temperature and process variation. The circuit is designed to drive the current tail of a photoreceiver TIA. The proposed architecture is based on a bandgap voltage reference and use an nMOS transistor at its output to produce a temperature compensation of mobility and threshold voltage (V_TH) over a wide range of temperature (-40 to 100°C) and process variation affecting V_TH. This technique has been confirmed by theoretical analysis and SPICE simulations using the TSMC CMOS 0.18μm process.
