The most basic characteristic of a Voltage Controlled Oscillator (VCO) is the manner in which the oscillator changes frequency as a function of voltage applied to its tuning port. As the state of the ...

The development of quantum computing systems relies on the ability to rapidly and precisely measure these systems' electrical properties, such as their underlying charge and spin states. These ...

With a tuning range from 0.5V to 2.5V, the ZV950 series of hyperabrupt varactor diodes meets the requirements of 3V frequency control and filtering systems. The diodes are reported to be characterized ...

Varactor (or “varicap”) diodes are used primarily in radio-frequency (RF) circuits to provide a capacitance that can be varied by changing the applied voltage. These types of diodes often are used for ...

Various configurations (Colpitts, Pierce, Clapp etc) are described in literature [Ref(1)]. Depending on the frequency requirements, various devices like MESFETs, pHEMTs, and HBTs can be used for VCO ...
