Title: Pradeep Bhardwaj: Innovator in Transducer and Oscillator Technologies
Introduction
Pradeep Bhardwaj is a notable inventor based in Concord, CA, with a strong focus on advancements in transducer and oscillator technologies. He holds five patents that showcase his innovative contributions to the field. His work emphasizes the importance of precision and efficiency in electronic systems.
Latest Patents
One of his latest patents is the "Ratiometric Transducer and Method." This invention features a transducer where the output signal is linearly proportional to the supply voltage or level of excitation. A drive circuit applies a drive signal to an element that changes according to the monitored condition, such as rotation or acceleration. The pickup circuit receives signals from the element and provides an output signal that corresponds to the monitored condition. The operating voltage supplied to the drive circuit is adjusted to ensure that both the drive signal and output signal remain proportional to the operating voltage.
Another significant patent is the "Crystal Oscillator and Method with Amplitude and Phase Control." In this invention, a crystal element is connected in a positive feedback loop with a charge amplifier and an integrator, maintaining the gain of the loop at a level of unity. Compensation is provided to offset the effects of shunt capacitance in the crystal element, ensuring precise phase control. In other embodiments, the crystal element is connected in a series feedback loop with a buffer amplifier, where the oscillation signal is maintained at a level that avoids distortion, clipping, and saturation.
