Abstract

1,245,552. Integrated circuit oscillators. ITT INDUSTRIES Inc. 21 April, 1970 [25 April, 1969], No. 18975/70. Heading H3T. A monolithic integrated oscillator circuit comprises a capacitor C which is charged through a circuit LS and discharged through a circuit ES when a switch S is closed, the switch being controlled by a threshold circuit SWS to close at an upper and open at a lower threshold voltage on the capacitor, the output being taken either from point A as a delta waveform or from the circuit SWS as a rectangular one. The output is amplified by an unspecified circuit AS. The charge and discharge circuits comprise transistors of complementary type and constitute constant current circuits which are adjustable by inputs E LS , E ES to vary the duty factor and frequency of the output. It may be arranged to vary E LS and E ES together in a manner to vary the frequency only. The threshold circuit includes a potentiometer, across one half of which is connected a further resistor controlled by a transistor which is switched with the switch S. This produces the differential between upper and lower threshold values, and can be adjusted by an input E sws - In an alternative arrangement a resistor R is connected to the capacitor and the switch S is replaced by a change-over switch between LS and LE.
