Annu Dabas, Kanchan Grover "Peak Detector using Low Voltage Operational Transresistance Amplifier", International Journal of Engineering Trends and Technology (IJETT), V58(3),110-113 April 2018. ISSN:2231-5381. published by seventh sense research group

Previously, peak detector was build using diode, capacitor and a voltage mode device i.e. Op-Amp. Due to emergence of current mode circuits, it is possible to design high gain, large bandwidth, high speed and low voltage analog signal processing and generating applications. OTRA (Operational transresistance amplifier) is in fashion to design these applications due to its various advantages. In this paper, peak detector is proposed using low voltage OTRA. This proposed circuit is simulated using PSPICE simulation for which OTRA is realized using 180 nm CMOS process with low power supply of +0.9V. The proposed circuit also provide very low power dissipation.
