摘要： Known quartz crystal resonators, such as flexural mode or length extensional mode, suffer from many drawbacks including high series resistance and the inability to be miniturised.
The present invention provides a torsional quartz crystal resonator overcoming the above disadvantages and moreover operating in the frequency range 200-600 kHz with a zero temperature coefficient and can be manufactured cheaply and easily using an etching process.
This is achieved by the plate quartz crystal which is normal to the z or optical axis being rotated about the electrical axis by a cut angle ø where -90°

摘要： A temperature-compensated oscillator circuit includes an oscillation element (17) and a floating gate MOS variable capacitor (14) having a three-terminal structure comprising an injection terminal (T I ), a capacitance terminal (T C ) and a ground terminal (T G ). The resistance ratio of a resistor network (21,22,23) and a fixed resistor (24) determines a DC bias voltage which is applied between the capacitance terminal (T C ) and the ground terminal (T G ) of the variable capacitor to effect temperature compensation.
