Title: Haideh Khorramabadi: Innovator in Integrated Receiver Technology
Introduction
Haideh Khorramabadi is a prominent inventor based in Palo Alto, California. She has made significant contributions to the field of integrated receiver technology, holding a total of eight patents. Her work focuses on advancements in tuner architecture, which have implications for various communication technologies.
Latest Patents
One of her latest patents is for a fully integrated tuner architecture. This invention describes an integrated receiver with channel selection and image rejection that is substantially implemented on a single CMOS integrated circuit. The receiver front end provides programmable attenuation and a programmable gain low noise amplifier. Frequency conversion circuitry utilizes LC filters integrated onto the substrate in conjunction with image reject mixers to achieve sufficient image frequency rejection. The filters are designed with multi-track spiral inductors and are tuned using local oscillators. Additionally, frequency planning is employed to provide further image rejection. The local oscillator signal generation methods include PLL out-of-band local oscillation and direct synthesis for in-band local oscillators. A differential crystal oscillator serves as a frequency reference, and differential signal transmission is used throughout the receiver.
