Abstract

The paper presents a new current-mode second order universal filter with single input and three outputs using two current feedback amplifiers, two grounded capacitors, two grounded resistors and only one floating resistor. The circuit implements lowpass, band-pass and high-pass filter functions simultaneously without changing configuration and passive components. All the passive components are grounded except one floating resistor. The grounded capacitors make circuit suitable for integration. The circuit has low active and passive sensitivities. Simulation results agree well with the theoretical analysis.
