Voltage-controlled oscillators (VCO) are one of the most essential building blocks in phase-locked loops and frequency synthesizers, which are required in all data communication and telecommunication systems for generating highly accurate timing reference sources. However, existing VCOs need a suppl.....

A new bistable liquid crystal display (LCD) is invented. It has many advantages over existing bistable LCDs, such as low voltage operation, permanent bistability, and fast switching. It can be used in smart cards and in low power applications. LCDs that are truly bistable under zero voltage bias a.....

In modern wireless communication systems, the receiver is to recover with high sensitivity and accuracy baseband signal data or messages, which have been transmitted or broadcasted by way of modulation on a radio frequency (RF) carrier. However, these conventional high frequency receivers comprise a.....
