  • AMPLIFIER WITH ADJUSTABLE INPUT AND FEEDBACK RESISTANCE
    Publication number: 20240223146
    Abstract: A programmable gain amplifier (PGA) circuit for adjusting a signal gain between a signal input and a signal output can include a differential-input amplifier which can include a first input node, a second input node, and a first output node, where the differential-input amplifier can be configured to amplify a difference in signal level between the first input node and the second input node for being provided on the first output node. The PGA circuit can also include a first configurable input impedance circuit, which can be arranged between a first signal input node and the first input node, which can be configured to provide a first specified input impedance value. The PGA circuit can also include a first configurable feedback impedance circuit, which can be arranged between a first signal output node and the first input node, which can be configured to provide a first specified feedback impedance value.

  • Method and system for high-speed detection handshake in universal serial bus based data communication system
    Patent number: 8176227
    Abstract: A USB system includes a USB hub, a USB device, and a USB bus interconnecting the USB hub and the USB device. The USB hub asserts a reset signaling on the USB bus to initiate a high-speed detection handshake. The USB hub and the USB device activate corresponding dual-mode squelch detectors in a first (handshake) mode of operation. The USB device transmits a device chirp signal to the USB hub. The USB hub responds with a sequence of hub chirp signals. The USB device detects the hub chirp signals and then the USB hub and the USB device establish a communication link in a high-speed mode of communication in accordance with USB 2.0. The dual-mode squelch detectors in the USB hub and the USB device can also be activated in a second (normal) mode of operation.
