Frequency divider for frequency synthesizer, has one transistor of one cell connected in parallel to short circuit transistor in which gate is connected so as to become conductor by a control signal to change a division rate

摘要

The frequency divider has cells (C1-C3) with an inverter (3) in which a transition is authorized by control transistors (M1, M4) assembled in series with the inverter. One (M4) of the transistors of one (C2) of the cells is connected in parallel to a short circuit transistor (M5) in which a gate is connected so as to become conductor by a control signal to change a division rate.
