UTILIZING MULTIPLE ANALOG-TO-DIGITAL CONVERTERS IN A CONVERSION CIRCUIT - A simplified explanation of the abstract

This abstract first appeared for US patent application 18184980 titled 'UTILIZING MULTIPLE ANALOG-TO-DIGITAL CONVERTERS IN A CONVERSION CIRCUIT

The abstract of the patent application describes a conversion circuit that includes two analog-to-digital converters (ADCs) to convert an analog voltage into digital output bits.

  • The first ADC converts the analog voltage to generate a first subset of digital output bits from the most significant bit (MSB) to a bit k, and a second subset of digital output bits from a bit k-1 to the least significant bit (LSB).
  • The first ADC also outputs a residual voltage after converting the bit k, which is then amplified by an amplifier stage.
  • The amplified residual voltage is then converted by the second ADC to generate extra digital output bits.

Original Abstract Submitted

Examples are disclosed related to analog to digital conversions. One example provides a conversion circuit comprising a first analog-to-digital converter (ADC) configured to convert an analog voltage to generate a first subset of digital output bits from a most significant bit (MSB) to a bit k and a second subset of digital output bits from a bit k−1 to a least significant bit (LSB) of the first ADC. The bit k is between the MSB and the LSB. The first ADC comprises a residual output configured to output a residual voltage of the analog voltage after converting the bit k. The conversion circuit further comprises an amplifier stage connected to the residual output and configured to generate an amplified residual voltage. The conversion circuit further comprises a second ADC connected to the amplifier stage and configured to convert the amplified residual voltage to generate extra digital output bits.
