titleOfInvention |
Circuitry and method for reducing area and power of a pipelince ADC |
abstract |
A pipeline ADC (analog-to-digital converter) ( 14 ) includes a residue amplifier ( 7 ) for applying a first residue signal (Vres 1 ) to a first input of a residue amplifier ( 11 A) and to an input of a sub-ADC ( 8 ) for resolving a predetermined number (m) of bits and producing a redundancy bit in response to the first residue signal. A level-shifting MDAC ( 9 A) converts the predetermined number of bits and the redundancy bit to an analog signal ( 10 ) on the a second input of the residue amplifier, which amplifies the difference between the first residue signal and the analog signal to generate a second residue signal (Vres 2 ). The MDAC causes the residue amplifier to shift the second residue signal back within a predetermined voltage range (±Vref/2) by the end of the amplifying if the second residue signal is outside of the predetermined voltage range. |
