Original Abstract

This paper presents a new low-voltage fully differential current feedback operational amplifier for ultra-low-voltage and low-power analog circuit applications. A bulk-driven technique is used to reduce the supply voltage requirement and also provides a rail-to-rail input voltage common-mode swing. The proposed circuit has been simulated using TSMC 0.18 µm n-well CMOS technology with a 0.5-V supply voltage. Simulation results show that the static power consumption of proposed circuit is 4.7 µW. The proposed circuit has been used to realize fully differential integrators and fully low-pass/band-pass second-order filters to express the performance of the new circuit.
