The paper presents a reconfigurable fully differential all pass filter based on CMOS differential voltage current conveyor. The proposed topology uses two differential voltage current conveyors along with two resistors and two capacitors. The phase angle of the realized fully differential all pass filter can be controlled through an n-bit digital control word. Thus the proposed filter topology provides increased immunity to external noise, reduced even-order harmonics, high resolution capability and reconfigurability. The proposed filter circuit is simulated by using PSPICE. The results thus obtained justify the theory.

A low-voltage second-generation current conveyor (CCII) and its oscillator application suitable for portable systems are proposed in the paper. The proposed current conveyor is based on an inverter-based low-voltage error amplifier and a current mirror. There are no on-chip capacitors in the proposed current conveyor, and it can be designed with standard CMOS digital processes and hence will reduce the cost of chip fabrication. Moreover, the architecture of the proposed circuit without cascoded MOSFET transistors is easily designed and suitable for low-voltage operation. The CCII could be operated in a very low supply voltage such as ±0.5 V. The proposed CCII has been fabricated with TSMC 0.18 μm CMOS process and applied to low-voltage CCII oscillator suitable for portable systems.

“…The feature is quite suited while designing analog blocks with easy configurability, so as to be employed in field programmable analog arrays (FPAAs). Simple analog blocks with this feature were reported earlier and further researched in most recent works [1][2][3]. Whereas configurability gives rise to the possibility of several electronic functions from a single topology, cascadability results in practical utility of analog blocks for designing more complex networks without additional coupling elements in form of buffers [4][5][6].…”

This paper presents some additional high input low output impedance analog networks realized using a recently introduced single Dual-X Current Conveyor with buffered output. The new circuits encompass several all-pass sections of first- and second-order. The voltage-mode proposals benefit from high input impedance and low output impedance. Nonideality and sensitivity analysis is also performed. The circuit performances are depicted through PSPICE simulations, which show good agreement with theory.
