Abstract :
In this paper a low-voltage CCII-based tunable oscillator is presented. The circuit makes use of new first and second generation current conveyors, designed to operate at typical supply voltages as low as 1.5 V, the minimum being 1.2 V. SPICE simulations, performed by 0.5 μm CMOS process from ALCATEL-MIETEC, well confirm the theoretical analysis. In particular, CCI and CCII models have been taken into account. Simulation results give a large tuning range (7-9.5 MHz), a total harmonic distortion lower than 1.5% and a 530 μW power consumption at 1.5 V supply.
