| Popis: | This study presents a new low-voltage fully differential current feedback operational amplifier for ultra-low-voltage and low-power analogue 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 a TSMC 0.18 µm n-well CMOS technology with a 0.5 V supply voltage. Simulation results show that the static power consumption of the proposed circuit is 4.7 µW. The proposed circuit has been used to realise fully differential integrators and fully low-pass / band-pass second-order filters to express the performance of the new circuit. |
