| 摘要 |
A voltage-controlled current source includes a current source having temperature dependency, a voltage source having process dependency, a first signal conversion circuit which generates second voltage having temperature dependency and process dependency by use of current of the current source and first voltage of the voltage source, a second signal conversion circuit which converts a first control signal used to control transfer conductance into a second control signal by using the second voltage as a reference, and a voltage-controlled current source circuit whose transfer conductance is controlled according to the second control signal.
