A 0.5 V fully differential transimpedance amplifier in 65-nm CMOS technology

Effects of Memristors on Fully Differential Transimpedance Amplifier Performance

“…Temperature variation analysis shows that in all cases bandwidth alterations are insignificant and gain deviations are considerably smaller in the memristor based design. Four designs which are based on [5] were compared and contrasted in terms of gain, frequency response, linear range, power consumption, area, total harmonic distortion and performance variations with temperature. To conclude, if fully differential feature is not required, designs with memristors give many advantages over the designs without them.…”

“…1. Schematic of the differential amplifier without memristors [5]. Equation 8 is derived by dividing Eq.6 by Eq.7, and similar for Eq.9.…”

“…The schematics of fully differential TIA is presented in Fig. 1 [5]. We propose to replace resistor R1, and transistors M6 and M9 with memristors, which allows to reduce the onchip area and power dissipation, and does not deteriorate the functionality of the circuit.…”

“…Communication between various devices is the principal idea of the IoT [1], [2] and the progress of transceivers plays a major role in the IoT development [1], [3], [4]. Amplifier is a fundamental element in any analog circuit for IoT applications, and a majority of transceivers include transimpedance amplifiers (TIA) [3], [5], [6], [7], [8]. IoT systems require low power devices and circuits with small on-chip area, and ability to tolerate temperature variations [1], [9], [10].…”

“…The use of memristors in various architectures have proven the to be efficient for the reduction of on-chip area and power consumption, comparing to the conventional CMOSbased designs [1], [2], [10], [15]. This paper compares the conventional TIA design shown in [5] and proposed CMOSmemristive modification, where one resistor, two CMOS transistors are replaced by memristors.…”
