Title: Innovations of Mohammad-Reza Sheikh-Movahhed

Introduction

Mohammad-Reza Sheikh-Movahhed is an accomplished inventor based in Ann Arbor, MI (US). He holds a total of 3 patents that showcase his expertise in the field of electronics and signal processing. His innovative contributions have significantly impacted the design and functionality of various electronic systems.

Latest Patents

One of his latest patents is the "Direct conversion pre-ADC frequency mixer." This system is designed for single path processing of identical, substantially identical, close, or interfering frequencies using a single analog-to-digital converter. The system receives multiple input signals at various frequencies, with front-end circuits filtering out the first and second frequencies. A mixer and a front-end oscillator work in conjunction with one of the front-end circuits to mix a front-end frequency with one of the first and second frequencies before reaching the analog-to-digital converter. The output of the mixer is combined with the output of one of the front-end circuits by a summer, and the analog input signal is converted to a digital output signal by the analog-to-digital converter. Notably, the first and second frequencies can be processed separately even if they are identical.

Another significant patent is the "FM radio receiver." This invention comprises a radio frequency tuning circuit that selects a frequency-modulated signal from an antenna and a local oscillator tuning circuit that tunes to an oscillating signal. This configuration converts the frequency-modulated signal to an intermediate frequency. The radio frequency tuning circuit is designed to continuously receive frequencies from both a first FM receiving band used in Japan and a second FM receiving band used in the US and Europe. The local oscillator tuning circuit allows for switching between inductance values and capacitance variable ratios, enabling the receiver to be set for lower heterodyne reception in Japan or upper heterodyne reception in the US or Europe. This design allows a single receiver to be configured for FM radio broadcasting in different regions without increasing the number of components.
