The paper provides a structure of a wide tuning center frequency range VCO (Voltage Controlled Oscillator). The VCO is completed on the base of oscillation theory and negative resistance structure. This circuit has a high stability of output voltage amplitude and can oscillate in a great range of frequencies.
A standing wave oscillator (SWO) is a perfect clock source which can be used to produce a high frequency clock signal with a low skew and high reliability. However, it is difficult to tune the SWO in a wide range of frequencies. We introduce a frequency tunable SWO which uses an inversion mode metal-oxide-semiconductor (IMOS) field-effect transistor as a… (More)
This paper introduces a new PLL architecture which uses resonant standing wave oscillator (SWO). The SWO uses varactors to tune the oscillator frequency by two means. Coarse tuning is achieved by setting the control voltages of a number of configuration varactors that participate in the oscillation. Fine tuning of the oscillator frequency is achieved by… (More)
