Voltage Controlled Integrator and Linear Quadrature-VCO Using MMCC

P. Venkateswaran, R. Nandi, Sagarika Das

Abstract


A Voltage Controlled Oscillator (VCO) based on the new multiplication-mode current conveyor (MMCC) building block is presented. The oscillator is realized using a double integrator loop (DIL) where a linear frequency (fo) versus the control voltage (Vc) tuning characteristics with quadrature sinusoid signal generation in a range of 40  kHz ≤ fo≤ 700   kHz had been experimentally verified. The foââ€â‚¬ sensitivity is low while the frequency stability factor (Sf more than 1) is high at satisfactory values of total harmonic distortion (THD ≈ 1.11%).
