This work presents a multi-channel high voltage analog multiplexer with digital calibration for battery management systems (BMS). For a high voltage battery management systems, the front end circuit must be able to accommodate input voltage up to tens of volts, perhaps even hundreds of volts. To realize a possible solution on silicon, the front end of BMS shall be fabricated using an advanced HV (high...
An RF front-end transceiver is implemented in standard 0.18-μm CMOS for V2.1 Bluetooth applications. All signal detection and gain calibrations are realized without the need of baseband control, but using an incoming Gaussian frequency-shift keying signal detection mechanism, auto low-noise amplifier gain mode selection, and autogain calibration with a combined programmable gain amplifier/received-signal-strength...
An RF front-end transceiver is implemented in standard 0.18 mum CMOS for V2.1 Bluetooth applications. All detections and calibrations are realized without baseband's feedback using an incoming GFSK signal detection, auto LNA gain mode selection and auto gain calibration with combined PGA/RSSI function. The DEVM performance of the transmitter is less than 6% and a 7.5 dB system NF is achieved in the...
Phasor Measurement Units (PMU), based on the synchronized measurement technology, are basic building blocks of wide-area monitoring, protection and control (WAMPAC) systems. The overall system performance of such WAMPAC systems highly relies on the proper functioning of all PMUs of the system that conform to the same high performance standards. However, ensuring a uniform performance compliance of...
