  • Differential output PGIA architecture
    Patent number: 10419014
    Abstract: The present disclosure provides a simplified, multiple-gain, front-end circuit for analog-to-digital converter systems. In an example, a front-end circuit for an analog-to-digital converter (ADC) can include first and second input amplifiers configured to receive an input signal, and a gain selection circuit coupled to the first input amplifier and the second input amplifier; the gain selection circuit comprising a plurality resistor strings, each resistor string including a plurality of resistors coupled in series, and wherein each string includes a first end node coupled to an output of the first input amplifier and a second end node coupled to an output of the second input amplifier.
    Type: Grant
