Abstract :
A current-controlled sinusoïdal oscillator based on the Wien bridge oscillator is presented. The circuit acts in current mode and uses a second generation current conveyor. Its oscillation frequency, which can be varied from 20 to 90 MHz is adjustable from the bias current of a floatting resistor. The circuit has been implemented from SGS THOMSON in a 2¿m BICMOS technology. Measurement results are obtained in good accordance with simulation ones. At 50 MHz, the total power consumption is 50 mW under 5 Volts.
