This paper presents a new voltage-mode (VM) universal biquadratic filter using differential difference current conveyor transconductance amplifier (DDCCTA) as an active element. The circuit employs one DDCCTA, two floating resistors and two floating capacitors which can realize five biquadratic filters, namely low-pass (LP), band-pass (BP), band-stop (BS), high-pass (HP) and all-pass (AP) into one single topology. For realizing these filtering functions, passive component-matching conditions, inverting-type and/or doubling-input signal requirements and changing circuit configuration are absent. The natural angular frequency and quality factor of the filter can be orthogonally controlled deliberately. The VM biquadratic filter using grounded passive components with high-input and low-output impedances can be obtained by adding an additional DDCCTA or differential difference current conveyor (DDCC). The simulation results with 0.5[Formula: see text][Formula: see text]m CMOS process from MIETEC are given to confirm the theoretical predictions and the experimental results are also included to verify the workability of the proposed structure.

A new simple dual-output second generation current conveyor (DO-CCII) circuit is proposed. Designed in a standard 0.5-μm CMOS process, the circuit operates at ±1.5 V supply voltages with a total power consumption of 106 nW. Main characteristics of the proposed DO-CCII are its simplicity, small silicon area consumption, and not suffering from the body effect of MOS transistors. The proposed circuit is employed to implement a first-order low-pass filter with upper -3 dB cut-off frequency of as low as 3.2 Hz.

This paper presents a dual mode, single input multioutput (SIMO) biquad filter configuration using single voltage differencing transconductance amplifier (VDTA), three capacitors, and a grounded resistor. The proposed topology can be used to synthesize low pass (LP), high pass (HP), and band pass (BP) filter functions. It can be configured as voltage mode (VM) or current mode (CM) structure with appropriate input excitation choice. The angular frequency (ω0) of the proposed structure can be controlled independently of quality factor (Q0). Workability of the proposed biquad configuration is demonstrated through PSPICE simulations using 0.18 μm TSMC CMOS process parameters.
