Abstract
An integrated semiconductor device including a frequency divide-by-two circuit comprising an inverter stage and a switching transistor (T2) which is controlled by a microwave input signal (E). The divider circuit includes an oscillator stage in that the inverter stage is at least equipped with a reactive element which in combination with the inverter stage forms a negative resistant network. The switching transistor is connected in parallel with this reactive element and the transmit time .tau..sub.0 of the switch is less than the transit time .tau..sub.2 of a signal propagating through the reactive element.
