(FDCCII). The proposed FDCCII is based on a fully‐differential difference transconductor as
an input stage and two class AB output stages. Besides the proposed FDCCII circuit
operating at a supply voltage of±1.5 V, it has a total standby current of 380 µA. The
applications of the FDCCII to realize a variable gain amplifier, fully‐differential integrator,
and fully‐differential second‐order bandpass filter are given. The proposed FDCII and its …
