In this work, we investigate Operational Transresistance Amplifier (OTRA) based square wave generator application. The proposed configuration presents single Operational Transresistance Amplifier (OTRA) with two resistors and one capacitor. The duty cyle of the proposed configuration can be adjusted with the help of varying input voltage and with the help of resistor and capacitor. OTRA as an active building block. The advantage of the proposed configuration electronically tunable and improves its duty cycle with the help of resistor and capacitor. The proposed work describes the circuit operation in SPICE Simulation using 0.18µm CMOS technology. A total harmonic distortion (THD) of 2.10 % with low power consumption is 0.79 - 0.82mW for the frequency ranges 7.92 Hz - 7.95Hz oscillation and total harmonic distortion (THD) of 0.4 - 0.58 % at the frequency ranges 7.90KHz - 795 KHz is achieved for excellent linearity.
