Integrated circuit device and method of dynamically modifying at least one characteristic within a digital to analogue converter module

摘要

An integrated circuit device comprises at least one digital to analogue converter module. The DAC module includes at least one current replicator component having a first channel terminal, a second channel terminal and a reference voltage terminal arranged to receive a reference voltage signal; the at least one current replicator component being arranged to moderate a current flowing between the first and second channel terminals based at least partly on the received reference voltage signal. The DAC module also includes at least one filter component coupled to the reference voltage terminal to perform filtering of the reference voltage signal.

1. An integrated circuit device comprising a digital to analogue converter (DAC) module, the DAC module comprising:
a current replicator component comprising:
a first channel terminal, a second channel terminal; anda reference voltage terminal arranged to receive a reference voltage signal, wherein the current replicator component is arranged to moderate a current flowing between the first and second channel terminals based at least partly on the received reference voltage signal; a filter component operably coupled to the reference voltage terminal of the current replicator component and arranged to perform filtering of the reference voltage signal; and a filter control module, wherein the filter control module is arranged to:
detect a state change of a digital input of the DAC module; anddynamically modify a characteristic of the filter component in response to detecting said stage change.
