Title: Naghmeh Sarkeshik: Innovator in Acoustic Technology

Introduction

Naghmeh Sarkeshik is a prominent inventor based in Cupertino, CA (US). She has made significant contributions to the field of acoustic technology, holding a total of 2 patents. Her innovative work focuses on enhancing the performance of film acoustically-coupled transformers.

Latest Patents

Sarkeshik's latest patents include the "Film Acoustically-Coupled Transformer with Increased Common Mode Rejection" and "Impedance Transformation Ratio Control in Film Acoustically-Coupled Transformers." The first patent describes a film acoustically-coupled transformer (FACT) that features decoupled stacked bulk acoustic resonators (DSBARs). Each DSBAR consists of lower and upper film bulk acoustic resonators (FBARs) with an acoustic decoupler in between. This design enhances the common-mode rejection ratio of the FACT by incorporating an inductor connected in parallel with a parasitic capacitor formed by the acoustic decoupler and electrodes of the FBARs. The second patent focuses on controlling the impedance transformation ratio in FACTs, where the FBARs of one DSBAR differ in electrical impedance from those of another, allowing for a transformation ratio greater than 1:m.
