ABSTRACT:
An oscillator circuit is disclosed using a capacitive voltage divider, the circuit being integratable in a monolithic integrated circuit chip. Currents are switched into and out of that one of the capacitors in the divider which is connected through inverters to the other capacitor in a feedback loop. Switching of the currents is controlled in another feedback loop involving a further inverter.
