A current-mode universal filter using a pair of four terminal p-type active current conveyors (CFCCIIp) is presented. The filter can simultaneously realise lowpass, highpass and bandpass responses. Realisation of the notch response does not require additional active elements. All the passive elements are grounded and the circuit has low sensitivity.
