<abstract>Operational Transresistance Amplifier (OTRA) is an inherently suitable active building block for analog VLSI applications, since the OTRA is not slew limited in the same fashion as voltage op amps [2]. It can provide a high bandwidth independent of the gain. Hence, it does not suffer from constant gain bandwidth product like voltage op amps circuits [8]. An Operational Transresistance Amplifier (OTRA) based phase detector circuit has been proposed, due to the fact that both input and output terminals of OTRA are characterized by low impedance. The proposed circuit is simple to realize and consists of two OTRA based comparators, a CMOS XOR circuit, buffer and an RC integrator.</abstract>
