Title:
LATCH DIVIDER
Document Type and Number:
WIPO Patent Application WO/2012/112671
Kind Code:
A3
Abstract:
A single stage divider is adapted to operate at very high frequencies. A differential input signal (INP, INM) (for example, with about 120GHz frequency) is divided by divider (100) to provide a differential output signal (OUTP, OUTM) with a lower frequency (for example, about one- half). The divider provides an LC resonator (102) using parasitic capacitances from the gates of transistors (Ql, Q2) together with inductances of inductors (LI, L2) to form an LC tank, thereby taking advantage of parasitic that normally degrade performance.
