“…The FDCCII structures that were reported in the literature employed large supply voltages, as high as 5 V [6] . However, in 2014, Kumngern et al introduced a low voltage structure [7] using the bulk driven technique [8] . The operating supply was reduced to 0.5 V. While the semiconductor industry races toward lower-technology nodes still in FDCC structures transistor technology, ranging from 0.35 μm to as large as 1.2 μm [5][6]9] .…”

In this paper, we present a new voltage-mode biquad filter that uses a six-terminal CMOS fully differential current conveyor (FDCCII). The FDCCII with only 23 transistors in its structure and operating at ± 1.5 V, is based on a class AB fully differential buffer. The proposed filter has the facility to tune gain, ωo and Q. A circuit division circuit (CDC) is employed to digitally control the FDCCII block. This digitally controlled FDCCII is used to realize a new reconfigurable fully-differential integrator and differentiator. We performed SPICE simulations to determine the performance of all circuits using CMOS 0.25 μm technology.

“…This was scaled down to 0.18 μm as reported in Ref. [7], but this challenge remains. Since the FDCCII block comes with the inherent advantage of realizing multifunctional filters using a single block [4,6,10] , this leads to an issue in the non-independent tuning of ω o and Q.…”
