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.doi:10.1109/prime.2011.5966237 fatcat:zpjo63qjojb3dozgf6mtvdzva4
