Low Voltage Integrated Astable Multivibrator Based on a Single CCII

In this paper we present a new low voltage (1.5V supply) astable multivibrator, implemented with a single CCII, that performs a controlled square wave generation. Complete theory calculations are addressed. Simulation results, obtained by means of Cadence simulator, are in a good agreement with theoretical expectations. Since the CCII has been implemented at transistor level, in a standard CMOS technology, the proposed multivibrator can be completely integrated. The maximum oscillation frequency obtained from simulations is about 50MHz.
