Pruthvi A. Chaudhari has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10416242
    Abstract: A device includes a plurality of high voltage cells (HVC) coupled to a plurality of resistors, and a controller. The plurality of HVC generates an output voltage that is higher than an input voltage to the plurality of HVC. The controller receives a reference voltage and an output voltage from a resistor of the plurality of resistors. The controller generates a signal responsive to a difference between the reference voltage and the output voltage. The controller forms a closed feedback loop with the plurality of HVC and the plurality of resistors. The generated signal is input to the plurality of HVC. A substrate of a resistor of the plurality of resistors is biased to an output of at least one high voltage cell of the plurality of HVC. Output of the at least one high voltage cell is input to another high voltage cell.

  • Patent number: 8229048
    Abstract: A method, apparatus, and system for minimizing ringing in a high speed channel between a transmitter and a receiver in a circuit, including a component for initializing an n-tap equalization filter. The n-tap equalization filter includes numerous taps, each associated with each of numerous jitter pulses received from the transmitter at the receiver and over the channel. Many of the jitter pulses are greater than two. Further, each tap occurs at a time-domain point related to a time of a corresponding jitter pulse included within the numerous jitter pulses. Moreover, a component for applying the n-tap equalization filter to a subsequent signal sent over the channel is also included.
