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.
