The cascaded regulator architecture benefits from enhanced PSRR at the cost of an increased voltage drop and a degraded power efficiency of the voltage regulator. Subthreshold MOS transistors are utilized as a feedback network instead of conventional polysilicon or N-well resistors in order to save standby current and silicon area. The standby current passing through the MOS transistors ladder is controlled by the number and the size of the devices. The worst-case design scenario in terms of stability (slow process corner) is used to guarantee enough phase margin of the loop.
2 We demonstrate that a symmetric single-ended cascode compensation technique can be used to stabilize the regulator over the full range of alternating load current, thereby eliminating the need of any additional active circuitry [10] or a dynamic bandwidth boosting technique [11]. In order to minimize the ground current, optimum pole-zero allocation of the loop gain transfer function has been investigated in time domain, rather than in the frequency domain. Moreover, a novel technique is introduced to enhance the PSRR beyond the performance which can be achieved using classical cascode compensation technique.
