High speed fully differential second generation current conveyor

In this paper, a high speed fully differential second generation current conveyor (FDCCII+) is presented. The proposed FDCCII+ is based on using fully differential buffer and class AB push-pull output stage with a new standby current control circuitry. The circuit is realized using 90 nm CMOS TSMC technology model under 1.2 V single supply voltage. The proposed realization of FDCCII+ input differential voltage dynamic range is from -0.45 V to 0.45 V. The total power dissipation of the circuit is 1.7 mW. The simulated bandwidth of the FDCCII+ is 254 MHz under 10 KΩ load at X and Z terminals. All the circuit simulations are done using Cadence Virtuoso SPECTRE circuit simulator.
