Abstract

This paper presents a micropower 1.2-V 0.18-μm CMOS temperature-compensated voltage-to-frequency converter for portable applications. Results show that the proposed converter has a power consumption of 60 μW (15 nW in sleep mode) operating over a (0.0 - 1.0 V) input voltage range with two different selectable output ranges, 0 - 0.5 MHz and 0.5 - 1 MHz. It achieves a relative error below 3 %, a gain error below 3.6 % and a linearity error of 0.004 % (14 bits) over the whole frequency span.
