ABSTRACT:
Signal sampler embodiments are provided for processing input signals along signal paths in response to mode-command signals. They include a follower transistor with a control terminal and a current terminal that establish at least part of a signal path. They also include a switched-capacitor network that receives signals from the current terminal in response to a first mode-command signal and that couple a selected one of a set of reference signals to the current terminal in response to a second mode-command signal. During a second mode-command signal, a bias switch is arranged to bias off the follower transistor by coupling a bias signal to the control terminal that approximates the selected reference signal. Accordingly, the amplitude of the reference signals can be increased to facilitate an increased dynamic range of the input signals without biasing the follower transistor into breakdown.
