Abstract
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.
