US Patent 11513546 Current generation circuit, drive circuit, and current adjustment method

A current generation circuit includes a metal-oxide-semiconductor (MOS) transistor having a source terminal coupled to one line of a power supply line and a ground line, a voltage generation circuit configured to generate a first voltage corresponding to a resistance value of wiring between the one line and the source terminal, and a control circuit configured to cause the MOS transistor to generate a predetermined current based on the first voltage.
