  • Programmable gain amplifier with programmable resistance
    Patent number: 11152904
    Abstract: A circuit includes an analog-to-digital converter (ADC). The circuit also includes an analog front end (AFE) having an AFE input and an AFE output. The AFE output is coupled the ADC's input. The AFE includes a programmable gain amplifier (PGA) having a first PGA input and a second PGA input. The PGA includes a first operational amplifier (OP AMP) with first and second OPAMP inputs. The AFE also including a programmable resistance circuit having a first programmable resistance circuit input and first and second programmable resistance circuit outputs. The first programmable resistance circuit input is coupled to the first and second PGA inputs. The programmable resistance circuit includes a resistor network having first and second balance resistances. The first balance resistance is coupled to the first and second OP AMP inputs, and the second balance resistance is coupled to the first and second OP AMP inputs.

  • Noise shaping in a digital-to-analog convertor
    Patent number: 10892770
    Abstract: Systems and methods are disclosed for a signal convertor comprising a resistor or current source coupled to a positive virtual ground node and a negative virtual ground node, wherein the resistor or current source is configured to switch from the positive virtual ground node (VGP) to the negative virtual ground node (VGN), wherein the switching of the resistor or current source results in a shaping of the low frequency noise from the resistor.
