Title: Manar Ibrahim El-Chammas: Innovator in Circuit Design

Introduction

Manar Ibrahim El-Chammas is a notable inventor based in Dallas, TX (US). She has made significant contributions to the field of circuit design, holding a total of 7 patents. Her work focuses on enhancing the performance and reliability of electronic components.

Latest Patents

One of her latest patents is titled "Track and hold with active charge cancellation." This invention involves a track and hold circuit that includes a primary sampling capacitor, a primary switching transistor, and a cancellation transistor. The primary switching transistor is designed to provide a track state that connects an input signal to the primary sampling capacitor and a hold state that isolates the input signal from the primary sampling capacitor. The cancellation transistor is coupled to the primary sampling capacitor and is configured to inject a charge that cancels any charge injected by the primary switching transistor during the hold state.

Another significant patent is "Analog to digital converter error rate reduction." This patent describes an analog-to-digital converter (ADC) that includes a comparator and a metastability detector. The comparator is configured to compare an input signal to a reference signal to determine if the input signal exceeds the reference signal. The ADC output is based, at least in part, on the comparator output. The metastability detector is coupled to the comparator and determines if the comparator is operating under metastable conditions, providing an output accordingly.
