ELECTRONIC CIRCUIT SYSTEM, TRACK HOLD CIRCUIT MODULE, ELECTRONIC CIRCUIT OPERATION CONTROL METHOD, AND PROGRAM THEREOF

摘要

Provided is an electronic circuit system which facilitates skew timing adjustment while preventing increase of power consumption. An electronic circuit system (1) includes: a track hold circuit module (10) formed by a hierarchical tree structure of track hold circuits which can track-hold an analog value of an analog signal; and a control signal generation module (60) which supplies an operation control signal to each of the track hold circuits in the hierarchical tree structure.  In the hierarchical tree structure, the number of track hold circuits of each of the hierarchies is stepwise changed from the first hierarchy of the input side to which an analog signal is inputted, toward the final hierarchy of the final output side as the number of hierarchies is increased.
