Feedforward Bulk-Driven Class AB Fully-Differential Second-Generation Current Conveyor (FDCCII)

Abstract:

In this paper, a feedforward bulk-driven class AB fully-differential second-generation current conveyer (FDCCII) is presented. Bulk-driven differential pair is employed for the input stage allowing the FDCCII to operate with rail-to-rail operation. Feedfoward technique is also incorporated into input stage to increase the DC gain and minimize the common mode gain. The circuit performance is verified using HSPICE in 0.18 μm CMOS technology. The simulation results show rail-to-rail input and output swings. The DC voltage transfer characteristic between ports Y and X and DC current transfer characteristic between ports X and Z shows good linearity. The bandwidths show 25.7 MHz (V_X/V_Y), 30 MHz (I_Z/I_X), respectively. The power dissipation is 267.5 μW.
