This paper presents a new Wien-type oscillator using electronically tunable current conveyors (ECCII). Unlike previous Wien-type oscillators, the condition of oscillation of the proposed circuit can be controlled electronically using the current gain of ECCII. The structure is realized using grounded resistor which is easy for developing as a voltage-controlled oscillator. The condition and frequency...
This paper presents a new electronically tunable voltage-mode universal filter with four-input one-output using six single-ended operational transconductance amplifiers, two grounded capacitors and two MOS resistors. The proposed circuit can realize of lowpass, bandpass, highpass, bandstop and allpass filters, without component-matching conditions and inverting input signals requirements. The natural...
