Title: Innovations of Anthony Junior Casillan

Introduction

Anthony Junior Casillan is an accomplished inventor based in Lewisville, Texas. He holds two patents that showcase his expertise in microelectromechanical systems (MEMS) and current modulation circuits. His innovative work has contributed significantly to advancements in sensor technology.

Latest Patents

One of his latest patents is a MEMS accelerometer self-test using an active mobile mass deflection technique. This invention involves a microelectromechanical system accelerometer sensor that features a mobile mass and a sensing capacitor. To self-test the sensor, a test signal is applied to the sensing capacitor during a reset phase of a sensing circuit. This test signal generates an electrostatic force that causes a physical displacement of the mobile mass, corresponding to a desired acceleration value. During the read phase, the variation in capacitance of the sensing capacitor due to the mobile mass's displacement is sensed. This variation is then converted to a sensed acceleration value, allowing for a comparison with the desired acceleration value to indicate any operational errors in the MEMS accelerometer sensor.

Another notable patent is the current modulation circuit. In this invention, a modulated digital input signal is processed through a conditioning circuit to create a first input signal. An error amplifier circuit receives this first input signal along with a second input signal, controlling a MOS transistor to generate a current-modulated output signal. The output signal is sensed to produce a feedback signal, which is selectively applied as the second input signal based on transitions of the modulated digital input signal.
