“…The regulator is usually composed of a switching stage and a feedback control circuit. Among the various elements in the DC-DC regulator [2][3][4], the oscillator and the error amplifier in the control circuit are important for the operation of the overall feedback control which requires a fast-dynamic response [5,6].…”

This paper introduces a design for a charge pump DC-DC boost regulator with an integrated low-voltage control circuit. With a charge pump and feedback circuits implemented in 0.35 µm CMOS technology, the proposed DC-DC boost regulator offers an efficient device solution for low-power applications. The proposed design employs an error amplifier, oscillator, and comparator in the control circuit which is designed with a supply voltage of 1.8–3.5 V and 2 MHz frequency. Stability is obtained via a pole-zero compensation in the feedback circuit. The charge pump regulator with four pump stages and the whole regulator circuit are analyzed using the Cadence simulation tool. Measurements of the fabricated 0.35 µm CMOS regulator show that the transient time of the error amplifier is controlled within 1.0 µsec and the output voltage is accurately controlled from 7.8 V to 9.4 V with 27–38 mV ripple and 4.5 mA maximum current.

“…The design of integrated DC-DC converter becomes important as light-weighted and thin electronic displays are in great demand. The display driver circuit usually exploits the on-chip DC-DC conversion systems (Forghani-zadeh et al, 2007;Wibben and Harjani, 2008;Lee et al, 2012) with off-chip LC filter because of the low power consumption, on the other hand, in the LED driver circuit, charge pump regulator (Park et al, 2012;Tanzawa and Tanaka, 1997;Lee et al, 2008) is preferred because it requires a low load current with relatively simple system. We propose the dual-mode boost converter with integrated low-voltage control circuit.…”

Purpose -The paper aims to design of dual-mode boost converter with integrated low-voltage control circuit is introduced in this paper. The paper aims to discuss these issues. Design/methodology/approach -The converter is operated either with LC filter or with charge pump circuit by the switch control. The control stage with error amplifier, comparator, and oscillator is designed with the supply voltage of 3.3 V and the operating frequency of 5.5 MHz. The compensator circuit exploits a pole compensation for a stable operation.Findings -The simulation test in 0.35 mm CMOS process shows that the charge pump regulator and DC-DC boost converter are accurately controlled with the variation of number of stages and duty ratio. The output-voltage is obtained to be 6-15 V within the ripple ratio of 5 percent. Maximum power consumption is about 0.65 W. Originality/value -This dual-mode is useful in the converter with a wide load-current variation. The advantage of the dual-mode converter is that it can be used in either high or low load current with a simple switch control. Furthermore, in charge pump regulator, there is no degradation of output voltage because of the feedback control circuit.
