Abstract
In this paper Operational Trans-Resistance Amplifier (OTRA) based voltage controlled oscillators are presented. They have a low component count and are easy to realize. The sensitivity (Hz per Volts) and tuning range can be configured just by controlling the value of the resistors. The oscillator circuit is insensitive to parasitic input capacitances and input resistances due to internally grounded input terminals of OTRA. PSpice simulations are given to verify the theoretical analysis.
