Title: John Pierdomenico: Innovator in Amplifier Technology

Introduction

John Pierdomenico is a notable inventor based in Temple, PA (US). He has made significant contributions to the field of amplifier technology, holding a total of 3 patents. His work focuses on enhancing the performance and efficiency of xDSL signals through innovative amplifier systems.

Latest Patents

One of his latest patents is titled "Boosting xDSL amplifier supply power on-demand." This invention provides systems and methods for increasing amplifier supply power on demand for multiple xDSL signals. The circuitry detects the signal or signals with the highest voltage and compares them to a threshold voltage. If the highest voltage exceeds this threshold, the corresponding amplifier supply voltages are increased to meet the amplification demand. Conversely, if the voltage does not exceed the threshold, the existing amplifier supply voltage is utilized.

Another significant patent is the "Amplifier system with digital adaptive power boost." This system includes a charge pump that supplies power to an amplifier. The charge pump can switch between a fixed input DC voltage and a boosted value in response to an increase in the input signal. It employs a switching transistor that activates only when the input signal exceeds a certain threshold. This amplifier system is particularly useful for envelope tracking of low duty cycle signals, such as xDSL or vDSL.
