Latest Patents

Sathwant Dosanjh holds a patent for a "Regenerative divider for up and down conversion of radio frequency (RF) signals." This invention focuses on generating local oscillator signals used for the up- and down-conversion of RF signals. A major issue in the design of modulators and demodulators is the leakage of local oscillator (LO) signals into the received signal path. His invention presents several highly integratable circuits that resolve the LO leakage problem. These circuits utilize regenerative divider circuits acting on oscillator signals running at a multiple or fraction of the desired LO signal frequency to generate in-phase (I) and quadrature (Q) mixing signals. Additionally, the circuits employ harmonic subtraction and polyphase mixers, as well as virtual local oscillator (VLO) mixing signals, which emulate local oscillator signals through complementary mono-tonal and multi-tonal mixing signals.
