Abstract
An analog to digital converter (ADC) includes a conversion circuit digitizing an input analog signal to produce an output digital signal. A current generator generates a constant bias current. A current mirror circuit includes an input transistor receiving the constant bias current, an output transistor in a mirroring relationship with the input transistor and generating a variable bias current, and a parallel transistor circuit selectively coupling a parallel transistor in parallel with the input transistor or the output transistor in response to a control signal. The control signal is representative of the conversion rate of the ADC. A buffer generates a common mode voltage for use by the conversion circuit, from the variable bias current.
