Latest Patents

Ashok Dhuna holds a patent for a "Phase locking loop frequency synthesizer." This invention involves a voltage-controlled oscillator (VCO) whose output signal frequency is proportional to the input voltage amplitude. In the first mode of operation, the VCO output is fed through a divider to a phase detector, which also receives a reference signal. The output from the phase detector is then processed through a loop filter and a passive controller, forming a closed phase-locked loop. To adjust the output frequency, the controller switches the circuit to a second mode where the VCO output is not fed back, and a constant voltage source is supplied to the VCO. This allows for a constant output frequency, which can be altered by adjusting a variable capacitor. The circuit can then switch back to the first mode, improving the locking time as the output frequency changes. This patent showcases his innovative approach to frequency synthesis, with 1 patent to his name.
