Abstract :
A macromodel for an analog frequency-to-voltage converter is described. The output voltage is linearly dependent on its input frequency. The maximum delay of the output voltage is one period of the input frequency. The input signal can have any amplitude or wave shape (square, sinusoidal or triangular), but the duty cycle must be 50% and its DC level must be 50%. This macromodel must be used with circuit simulation software which has models for switches. The operation of the macromodel is described, and the results of several examples are presented
