Latest Patents
Kirk Su holds a patent for a highly configurable capacitive transducer interface circuit. This transducer interface circuit is designed for use with capacitive sensors. The interface circuit, provided on an application-specific integrated circuit (IC), includes numerous trims and adjustments that allow it to operate with differential, balanced-pair sensors or a single-ended sensor. The circuit features a capacitive adjustment section and a capacitive trans-impedance amplifier section, which are configured with capacitor adjustment controls and gain adjustment controls. These controls, along with others, are provided as control registers. The capacitive trans-impedance amplifier section periodically reverses the voltages across the sensor, while the capacitive adjustment section integrates excess charge caused by differences in capacitance. Additionally, a low-pass filter section provides bandwidth adjustment without requiring any external components. An output buffer section includes further trim controls for gain and offset, governed by an offset selection bit that adjusts the output range to be optimally suited for the sensors.
