Abstract :
This paper presents a high performance 1.2 V-0.18 μm CMOS voltage-to-frequency converter (VFC) that can be used either in single or differential mode. The proposed VFC works over the entire input range with output frequencies ranging between 0.1 and 1.0 MHz. Its operation is ratiometric, with low power consumption (80 μW), allowing its use in battery operated systems. It achieves high linearity (0.015 %) for a temperature range of -40 to +120 oC.
