چکیده
The advent of differential voltage current conveyor(DVCC) has opened up new avenues in analog circuit design. In the present work, a DVCC has been employed to designcurrent-mode first-order continuous-time analog filters. Parameter tunability is achieved by the use of a two-MOSFET electronicresistor which exhibits variation in resistance in accordancewith a control voltage. The proposed circuits are amenable formonolithic integration by virtue of the fact that only MOSFETsand grounded capacitors are utilized. Circuit simulations usingPSPICE yielded promising results.

Electronically Tunable Minimum Component Biquadratic Filters for Interface Circuits
In this paper, two new electronically tunable filter configurations are proposed. The proposed filters operate current-mode (CM), voltage-mode (VM), transimpedance-mode (TIM) and transadmittance-mode (TAM). The first configuration realizes second-order VM band-pass and TAM high-pass filter characteristics from the same configuration. The second one realizes second-order TIM band-pass and CM low...

In the last two decades, current-mode (CM) circuits have received more attention. These types of circuits offer many advantages such as wider bandwidth, bigger dynamic range, better linearity and more IC suitability when compared with voltage mode (VM) topologies [1, 2]. In addition to this, electronic tunability is also one of the other important issues in electronic design since it allows us ...
