Digital divider for low voltage LOGEN. LOGEN is a local oscillator generator. One implementation presented herein provides for a pseudo-complementary metal-oxide-semiconductor (CMOS), in that, it is not a true CMOS type circuitry that has no DC current dissipation, but nevertheless does operate well at relatively high frequencies and relatively low power supply voltage levels. Appropriately placed p-channel metal oxide semiconductor field-effect transistors (P-MOSFETs) and n-channel MOSFETs (e.g., N-MOSFETs) are employed to provide for an all digital divider circuitry. In some embodiments, four active circuitry element levels are stacked between a power supply voltage and ground voltage level. In other embodiments, three active circuitry element levels are stacked between a power supply voltage and ground voltage level. The three active circuitry element levels embodiment provides for a greater area savings (e.g., because of the fewer elements) and also provides reduced input capacitance than the four active circuitry element levels embodiment.
