New circuit configurations for realizing bandpass and iowpass current-mode second-order filters are proposed. Each configuration uses a single first-generation current conveyor, a transconductance amplifier, three grounded capacitors, and two resistors at most. The parametersω0andω0/Q0of the bandpass and lowpass realizations are not interdependent and, therefore, single element control of the bandpass and lowpass characteristics is possible. Also, the feasibility of realizing a single element current-controlled sinusoidal oscillator is considered.

Transconductance Amplifier

A novel current-mode active filter topology using a first generation current conveyor (CCI) and an operational transconductance amplifier (OTA) is presented. Using this topology, grounded-capacitor biquadratic bandpass and lowpass filter sections, with at most five one-port passive elements, are realized. In these realizations, the parameterω0can be adjusted without disturbing the parameterω0/ Q0

A Current

This research article explores the possible applications of voltage differencing current conveyor (VDCC), as a current mode universal filter and a sinusoidal oscillator. Without the need for an additional active/passive element, a very simple hardware modification makes it a dual-mode quadrature oscillator from the filter configuration. Both the proposed circuit requires only two VDCC and all grounded passive elements, hence a preferable choice for integration. The filter has some desirable features such as availability of all five explicit outputs, independent tunability of filter parameters. Availability of explicit quadrature current outputs, independence in start and frequency of oscillations, makes it a better oscillator design. Apart from prevalent CMOS simulation results, VDCC is also realized and experimentally tested using the off-the-shelf integrated circuit. All the pen and paper analysis such as non-ideal, sensitivity and parasitic analysis supports the design.
