This paper proposes a new approach to implement a multiphase sinusoidal oscillator using loop-back of n-cascaded high-pass filters form. Two basic CMOS Multiple Outputs Operational Transconductance Amplifier (MOOTA) and grounded capacitors are constructed as a current-mode high-pass filter. Gain and frequency response of high-pass filter can be(More)
This article presents a realization of electronically tunable current-mode Elliptic ladder low-pass filter using CCCIIs. The passive RLC ladder filters prototype and signal flow graph method (SFG) are employed for synthesis. The CCCII-based lossy, lossless integrators and current attenuator are required for the circuit realization. The proposed filter(More)
This paper presents a tunable CMOS-based third-order low-pass filter that can be operated in high frequency. The proposed low pass filter is designed based on Elliptic Ladder low-pass filter prototype. The proposed filter structure is constructed by using two lossy integrators and a lossless integrator. The proposed filter comprises only 18 transistors. The(More)
