JITTER INSENSITIVE SIGMA- DELTA MODULATOR |
摘要 |
<p>A sigma-delta modulator for forming a digital output signal representative of a voltage level of an input signal, the sigma delta modulator having a node arranged to receive a current flow that is representative of the voltage level of the input signal and on whose voltage the digital output signal is dependent, the sigma-delta modulator comprising a plurality of capacitive elements for smoothing the current flow, each capacitive element being connected at one end to the node and at its other end to a respective switch unit and a plurality of switch units, each switch unit being arranged to connect the respective one of the capacitive elements to either a first voltage level or a second voltage level in dependence on the voltage at the node so as to provide feedback that affects the voltage at the node.</p> |
