Latest Patents

One of his latest patents is titled "Compact phase shifter circuit using coupled lines." This invention provides a switched-line phase shifter designed to create a differential phase shift between switched transmission paths. The design incorporates Schiffman sections of lengths that are non-integer multiples of quarter-wavelength, ensuring that no isolation points occur over the operating frequency range. This innovative approach allows for a space-efficient implementation of the phase shifter, utilizing switches to alternately combine and isolate Schiffman subsections.

Another significant patent by Arvind K Sharma is the "Quenchable VCO for switched band synthesizer applications." This VCO is adapted for use in switched band synthesizer applications and is formed from a heterojunction bipolar transistor (HBT) in a common collector configuration. The inclusion of a p-i-n diode in the quenching circuit minimizes the loading on the phase noise of the HBT oscillator, resulting in improved performance. The design also reduces frequency pulling and spurious oscillation, making it a valuable advancement in VCO technology.
