Abstract

The paper describes a new CMOS current LC-oscillator using an inductive effect observed in the current (low impedance) input terminal of a current conveyor. The calculation of the equivalent inductance and its Q-factor is given. The oscillator is then realized by a simple connection of a capacitor between this current input and output of the current conveyor. To control the oscillation amplitude, a resistor is connected between the conveyor output and ground. The results of calculations are verified using simulations of the circuit designed for 0.18 μm CMOS technology.
