Abstract
- A dual-path capacitor multiplier (DPCM) technique is proposed for onchip frequency compensation. The DPCM uses two currents to charge and discharge a compensation capacitor concurrently. Consequently, the equivalent capacitance is amplified dramatically with slight increase in silicon area and power. Thanks to the DPCM, the transient response of the DC-DC converter has improved significantly because of the small compensation capacitor. Experimental results demonstrate converter stability and transient response. The transient recovery time of a 450 mA step load change is <30 μs. With the proposed technique, the compensation capacitor is shrunk significantly and adding the compensation resistor would have helped in improving transient response. [ABSTRACT FROM AUTHOR]
