<abstract>Operational Transresistance Amplifier (OTRA) is a Current Controlled Voltage Source (CCVS) characterized by low impedance, thereby producing circuits insensitive to stray capacitances. This paper presents an OTRA implementation of a multimode semi Gaussian (S-G) shaper that supports voltage and transimpedance modes of operation. A comparative study of performance indicators like Signal to Noise Ratio (SNR) and Total Harmonic Distortion (THD) is included. The results obtained from SPICE simulations using 0.5 μm CMOS technology model parameters depict a perfect Gaussian shaped output waveform that contributes towards decreasing Inter Symbol Interference (ISI) by overcoming irregularities during transmission of pulse in the channel.</abstract>
