Abstract

This article proposes a high performance frequency-to-voltage converter (FVC). The proposed circuit has a simple structure which consists of just only one current source, one Logic Controller Block (LCB), two capacitors and four MOS transistors to generate different phase shifts in time domain using the switched capacitor control technique. To validate the feasibility of the proposed circuit and its theoretical operation, the circuit has been simulated by using the PSpice simulation program. The proposed circuit provides the output voltage dependent on the input signal frequency which can operate in the wide range of frequencies varying from 2.5 to 125 MHz, as well as, providing the stable output voltage levels by the number of N of approximately 8 cycles of input signals with high accuracy of 0.4 %. The power consumption of the circuit is relatively low at about 0.25 mW at 5 V supply voltage.
