CURRENT OUTPUT CONTROL DEVICE, CURRENT OUTPUT CONTROL METHOD, DIGITALLY CONTROLLED OSCILLATOR, DIGITAL PLL, FREQUENCY SYNTHESIZER, DIGITAL FLL, AND SEMICONDUCTOR DEVICE

摘要

A current output control device is provided that includes: a current cell array section including plural current cell circuits that are each connected in parallel between a first terminal (power source) and a second terminal (ground) that connect between the first terminal and the second terminal in by operation ON so as to increase control current flowing between the first terminal and the second terminal; and a code conversion section (decoder) that generates signals (row codes, column codes) to ON/OFF control current cells so as to change the number of current cells that connect the first terminal and the second terminal according to change in an externally input code and that inputs the generated signals to the current cell array section.
