An object of the disclosure is to provide a slope enhancement circuit, comprising an amplifier and a specific arrangement of capacitors and switches, further comprising a current digital to analog converter (IDAC), in a switched regulated current mirror. A method of sample and hold exploits the transient dynamics of the switched current mirror, to enhance the output current slope during PWM operation. A further object of the disclosure is to provide a low power, high speed switching type of regulated current mirror architecture. Still further, another object of the disclosure is to provide quick response to a sudden demand in current with a high degree of accuracy. Still further, another object of the disclosure is to provide a significant savings in circuit area.
