This paper proposes the design of a mixed-mode universal biquad configuration, which realizes generic filter functions in all four possible modes, namely voltage mode (VM), current (CM), transadmittance (TAM), and transimpedance (TIM). The architecture employs two differencing buffered amplifiers (VDBAs), resistors capacitors, can provide lowpass (LP), bandpass (BP), highpass (HP), bandstop (BS...

New Voltage Differencing Differential Input Buffered Amplifier (VD-DIBA) based lossless grounded and floating inductance simulation circuits have been proposed. The proposed grounded simulated inductance circuit employs a single VD-DIBA, one floating resistance and one grounded capacitor. The floating simulated inductance (FI) circuits employ two VD-DIBAs with two passive components (one floati...

This paper presents a first of its kind canonic realization of active RC (ARC) sinusoidal oscillator with non-interactive/independent tuning laws, which simultaneously provides buffered quadrature voltage outputs and explicit quadrature current outputs. The proposed circuit is created using a new active building block, namely the Z-copy controlled-gain current differencing buffered amplifier (Z...

In this paper, a first-of-a-kind mixed-mode universal filter employing three VDBAs and passive components, is proposed. The operates in all four modes provides five responses, namely voltage-mode (VM), current-mode (CM), trans-impedance-mode (TIM), or trans-admittance-mode (TAM). Additionally, the same topology can also work as CM single-input-multi-output (SIMO) filter. A state-of-the-art comp...

In the present paper a voltage mode differentiator (First order high pass filter) and voltage mode integrator (First order low pass filter) have been proposed by using current-controlled current differencing buffered amplifier (CCCDBA). In the present work, an effort has been made to control the first order filters parameters electronically, adjusting bias current of CCCDBA. Here, in each circu...

The conventional integrated-circuit operational amplifier (IC op amp) is typically designed for split power supplies (±15 ...

In this paper, design and analysis of a novel current-mode defuzzification circuit is presented. The proposed defuzzification circuit is based on current-mode four-quadrant multipliers that have been constructed with simple current squarer and current differencing buffered amplifier (CDBA). This circuit has capable of high linearity, simple structure, and wide input current range. The defuzzifi...
