Abstract

Current-to-voltage converters are important building blocks in analog-mixed signal processing circuits. In this paper, two very simple circuits of transimpedance amplifier used to realize a linear current-to-voltage conversion are presented. The circuits operation is not based on any charge accumulation process and the implementation of the circuits does not require any linear capacitance. The gain of the conversion and the dynamic range are adjustable so that the users of the circuits can make the best trade-off to optimize the results in specific applications. The circuits can be fabricated using a CMOS single poly technology which facilitates applications of the circuits in mixed signal applications
