ABSTRACT:
A prescaling stage includes bistable circuit in turn including respective master and slave portions inserted between a first and a second voltage reference and feedback connected to each other. Each portion is provided with at least one differential stage supplied by the first voltage reference and connected, by a transistor stage, to the second voltage reference, as well as a differential pair of cross-coupled transistors, supplied by output terminals of the differential stage and connected, by the transistor stage, to the second voltage reference. Advantageously, each master and slave portion includes a degeneration capacitance inserted in correspondence with respective terminals of the transistors of the differential pair.
