“…The same trend applies to subsequent stages. This method makes the output voltage drop of an MSMO DDC similar to that of an MSSO DDC; therefore, the output voltage of a tapered MSMO DDC is also calculated using (3). The use of the tapered structure improves η by reducing the output voltage drop and lowering the thermal power consumption.…”

“…Handheld and portable devices such as wearable or implantable biomedical systems and wireless sensors or actuators for the internet-of-thing (IoT) applications -where a battery or a wireless power link is used to supply power to the system -mandate the use of low-voltage and power-efficient design methods [1], [2]. Even though lowering the supply voltage may seem to be a viable choice in reducing the power consumption and the overall form factor of the system (e.g., shrinking the battery size), higher levels of supply voltage are sometimes required due to the existence of high-power blocks such as neural stimulators, RF power amplifiers, and on-chip flash memories [3], [4], [5]. In particular, brain stimulation circuits in a bidirectional brain-machine interface (BMI) system must use a high-voltage power supply so as to sink/source current from/to the brain tissue.…”

This paper presents an analytical model for calculating the output voltage and the power efficiency of multi-stage multi-output (MSMO) DC-DC converters (DDC) that use charge pump cells for boosting the voltage. Various cases such as multioutput current consumption and its effects on the output voltage and the power efficiency are studied. Based on the model, a tapered design approach is proposed that can bolster the power efficiency and lower the output voltage drop of MSMO DDCs. Moreover, a charge-pump-based DDC is introduced and designed to verify the proposed model. Simulation results using a standard high-voltage 180-nm CMOS technology affirms the accuracy of the presented model.

“…The required power supply voltage is usually a different attribute to its broad application scenarios. Therefore, the charge pump with fixed voltage cannot meet the different power supply requirements, which requires a voltage-adjust charge pump to provide a variety of output voltages or currents [1].…”

In this paper, a new closed-loop charge-pump circuit with adjustable output voltage and an on-chip compensation technique is proposed. The environmental temperature and process corner can be detected with an on-chip detection circuit and automatically feedback an adjusted reference voltage. With this, the magnitude of the charge-pump output voltage with Pulse-Width Modulation (PWM) can be compensated. The charge-pump circuit is designed and verified with a 180 nm Bipolar-CMOS-DMOS (BCD) process, and its output voltage at different process, voltage, and temperature (PVT) is controllable with low ripple. There are three selections for adjusting the output voltage: +5 V/+7 V/+10 V shifts, with the supply voltage ranging from 5 V to 32 V. It can remain tunable and stable at any shifts. The maximum deviation is ±0.265%, and the maximum load current can reach 30 mA. The ripple voltage is less than 0.3% (Δ Vripple/Vout) underthe maximum load. The Monte Carlo simulation results show that the worst case of the process sensitivity (σ/μ) is 0.1%. The charge-pump core area is 0.308 mm2, and the power consumption is 4.753 mW. The circuit can produce high-precision output and is suitable for high-side driving IC applications.

“…It is a fundamental difference of approach compared to analog circuits [5]. The experimental part including simulation of real properties of the cross-coupled charge pump [5] and their comparison with other architectures (Dickson charge pump, a static charge pump) has been done [1][2][3][4], [6], [7]. However, a design process of the circuit has not been known yet.…”
