FEED FORWARD DOUBLE-SAMPLING MODULATOR

摘要

Representative implementations of devices and techniques provide analog to digital conversion of an analog input. A multistage modulator using a feed-forward technique can alternately convert integrated samples of the analog input to digital representations. For example, the modulator is arranged to alternately output the digital representations to form a digital representation of the analog input.

1. An electronic device, comprising:
a first integrator stage arranged to integrate an input signal, an output of the first integrator stage arranged to be coupled to an input of a first comparator stage or to an input of a second comparator stage, based on a control signal; a second integrator stage coupled in cascade to the first integrator stage, an output of the second integrator stage arranged to be coupled to the input of the first comparator stage or to the input of the second comparator stage, based on the control signal and/or another control signal; and a multiplexer arranged to receive an output of the first comparator stage and an output of the second comparator stage and to alternately output the output of the first comparator stage and the output of the second comparator stage.
