摘要： Systems, methods, and apparatus for use in biasing and driving high voltage semiconductor devices using only low voltage transistors are described. The apparatus and method are adapted to control multiple high voltage semiconductor devices to enable high voltage power control, such as power amplifiers, power management and conversion and other applications wherein a first voltage is large compared to the maximum voltage handling of the low voltage control transistors. A DC/DC power conversion implementation from high input voltage to low output voltage using a novel level shifter which uses only low voltage transistors is also provided. Also presented is a level shifter in which floating nodes and high voltage capacitive coupling and control enable the high voltage control with low voltage transistors.

摘要： A tunable acoustic wave filter is switchable between band-pass and band reject characteristic. The filter comprises in a T-ype arrangement a first and second series resonator (82A...82N, 83A...83N), each with a switch in parallel (182A...182N, 183A...183N), and a third resonator (84A...84N) to ground. The first and second series resonators have differing resonance and anti-resonance frequencies. Depending on the position of the two switches the filter can operate with band-pass or band reject characteristic. Each resonator may have variable capacitors in parallel and in series to allow for tunability of the filter characteristic.
