Item type:Publication, Modular Class-AB Current Multiplier Based on Fully-Differential Hyperbolic Transconductor(2021-05-26)This paper presents a new class-AB current multiplier using fully differential hyperbolic sine transconductors based on floating-gate transistors. The proposed multiplier is developed from a hyperbolic sine multiplication identity which inherently provides a class-AB operation. The proposed multiplier was designed using 0.35 μm AMS CMOS process. Simulation results show that the proposed multiplier achieves -30 dB THD for high input modulation index of 23 while utilizing power consumption of 60 nW under a supply voltage of 3 V. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Ultra-low-power, modular, class-AB current multiplier(2019-07-01)This paper describes a modular class-AB current multiplier which provides the good linearity, the linearly tunable conversion gain and the robustness to process mismatch. The proposed multiplier is derived from a hyperbolic sine multiplication identity, and was designed and simulated using 0.35 μm AMS CMOS process. Simulation results show that the improved linearity, linearly tunable conversion gain and better process variation robustness can be achieved while utilizing lower power consumption and the slightly higher number of transistors compared to the state-of-the-art class-AB current multiplier.
