摘要：
The paper is focused on the design and analysis of a Voltage-to-Frequency Converter (VFC) that was implemented in 130 nm CMOS technology. The proposed VFC was designed using the bulk-driven technique and can reliably work with the power supply voltage of 0.4 V. Since its basic building block is a Fully Differential Difference Amplifier (FDDA), the proposed VFC has a differential output. Therefore, the high output frequency dynamic range (Delta f(OUT) 3.45 kHz for the input range of 0-10 mV) as well as high sensitivity (348.8 Hz/mV) were obtained. The presented VFC can be used in complex ultra-low-voltage systems, where it would provide on-chip current consumption measurement.
