ABSTRACT:
Monolithically integrable squarewave pulse generator having a capacitor acted upon by two bucking constant-current sources, the capacitor having one terminal connected to the two constant-current sources as well as to a non-inverting input of an operational amplifier connected as a Schmitt trigger, and the capacitor having another terminal tied to reference potential, one of the constant-current sources being operative for charging the capacitor, including a third current source connected to the one capacitor terminal connected to the two constant-current sources for aiding the one constant-current source in charging the capacitor, the third current source being responsive to an adjustable potential of the one capacitor terminal; and the Schmitt trigger having an output connected through a decoupling element to signal output of the squarewave pulse generator.
