Abstract

The operation of current conveyor circuit is similar to an operational amplifier and a current conveyor circuit has the characteristics such as good linearity and stability. In this paper, a frequency-to-voltage converter circuit is designed by using a current conveyor circuit. The supply voltage is 5volts and the designed circuit is simulated by HSPICE. The range of the input frequency is from 4kHz to 200kHz. From the simulation results the error of the output voltages is less than from -1.3% to +2.5% compared to the calculated values.

전류 컨베이어 회로의 동작은 연산증폭기와 유사하며, 우수한 선형성과 안정성을 가지고 있다. 이 논문에서는 전류 컨베이어 회로를 이용하여 주파수 신호를 아날로그 전압 신호로 변환하는 회로를 설계하였다. 회로는 공급전압 5volts에서 동작하도록 설계하였으며, HSPICE 시뮬레이션을 통하여 결과를 분석하였다. 회로의 동작 범위는 4kHz 이상 200kHz 이하의 주파수에서 출력 전압의 에러는 +2.5% ~ -1.3% 이내 이었다.
