An apparatus comprises a cross-coupled differential amplifier, an inductive-capacitive (LC) tank circuit, and a low-noise voltage supply. The inductive-capacitive (LC) tank circuit is generally coupled in a feedback path of the cross-coupled differential amplifier. The LC tank circuit generally ...

The main goal of this work is to design a radiation-hard oscillator to be integrated into a phase-locked loop (PLL), compliant with (but not limited to) SpaceFibre protocol requirements, which is able to support the 6.25 GHz frequency. The full custom schematic and layout of the LC-VCO ...
The accuracy of capacitance equations for varactors is improved by modeling the 4th terminal of MESFET (substrate) device and modeling the channel length effect on capacitance tuning.University of Colorado at Colorado Springs.Lotfi, Younes.University of Colorado at Colorado Springs....
The first stage amplifier receives a control voltage input signal, which would typically be produced at the output of a loop filter in a PLL, and produces a conditioned control voltage output signal at its output, which is connected to the drain of the diode-connected transistor. The purpose ...
With this change in size and speed, alternative designs for voltage controlled oscillator tanks or VCOs (and other components of PLLs) are being developed. Here, an LC VCO with a correction circuit (for linearizing the frequency versus control voltage characteristics of the VCO) is described ...
As such, the PLLs have both decreased in size and increased in speed, following the same trend as all other microelectronics. With this change in size and speed, alternative designs for voltage controlled oscillator tanks or VCOs (and other components of PLLs) are being developed. Here, an...
