Title: Innovations of Peter Real

Introduction

Peter Real is an accomplished inventor based in Groveland, MA (US). He has made significant contributions to the field of electronics, particularly in the development of advanced amplifiers and analog-to-digital converters. With a total of 4 patents to his name, Real continues to push the boundaries of technology.

Latest Patents

One of his latest innovations is the "Current mode sample-and-hold amplifier." This device features a sample-and-hold amplifier where the held signal is represented as a voltage across a capacitor, while all other signals are represented as currents. The design includes a summing node where the input current and feedback current are combined to produce a difference current. In tracking mode, this difference current flows through a closed hold switch to the input of an integrator, which accumulates the difference current onto the hold capacitor, creating the hold voltage. This voltage is then converted into a feedback current by a transconductance amplifier, ensuring accurate gain and linearity.

Another notable patent is the "Analog-to-digital converter employing a pipeline multi-stage architecture." This pipelined multi-stage ADC allows residue signals to be passed between stages as currents. The sample-and-hold circuits are designed to be current-in/current-out structures, with a voltage representation of the analog signal provided as input to the flash converter within the quantization loop of each stage. This innovative design includes additional comparators and segments in the DAC of each stage, enabling the conversion of inputs above full scale and below zero, while also generating output codes.
