MODIFIED CURRENT MIRROR CIRCUIT FOR REDUCTION OF SWITCHING TIME |
摘要 |
A current mirror circuit connectible to an amplifier circuit to set a bias point thereof includes a current mirror circuit, and a bias resistor connected thereto. The bias resistor is connectible to the amplifier circuit. A first helper circuit is connected in parallel with the bias resistor, and is selectively activated for a first predetermined duration by a first control signal. The activated first helper circuit defines a lower resistance path relative to the bias resistor to shorten a rising transient response of the amplifier circuit as the current mirror circuit is activated. |
