“…The ASICs are mounted on empty chip sockets for single performance measurement, as well as for measurement The high DC voltage up to 120 V is generated from a 3.7 V nominal DC supply at a maximal load current I L = 100 μA based on a modified Pelliconi charge pump structure [10]. This modified design adopts a dynamic bulk-biasing technique [17] to improve the output voltage saturation that a conventional Pelliconi charge pump presents [18].…”

Integration of a reconfigurable antenna module for handheld applications employing a set of novel technologies is demonstrated. A low profile dualband hybrid dielectric resonator antenna (DRA) based on glass-ceramics and a tunable matching network (TMN) based on ferroelectric varactors with a maximum biasing of 90 V form a reconfigurable antenna module. The control of the antenna module is performed by a 120 V CMOS high voltage (HV) charge pump with an 8-bit digital analog (D/A) converter generated from a 3.7 V battery. Adaptive impedance matching at the lower band of 1.9 GHz is carried out by the TMN when the dualband antenna is exposed to different operation scenarios. Meanwhile, the upper band located at a frequency of 5.1 GHz exhibits an almost negligible influence due to the inherent detune resistance characteristic of the high permittivity DRA.

“…A review of the prior art showed that in no other work something with sufficient voltage gain given the area and power restrictions of mobile applications has been implemented. In [10] and [13], high voltage gains were achieved, but at the cost of using an extremely large area. In [14], a small area was used for a charge pump, but the voltage gain was much lower than the required voltage gain of this work.…”

This paper presents two variants of a high step-up ratio charge pump for high voltage micro electro-mechanical system and condenser microphones. The implementations are based on an additive charge pump topology where respectively 46 and 57 cascaded stages are used to generate an output voltage of 182 V from a supply voltage of 5 V. The two charge pumps have been fabricated in a 180 nm SOI process with a breakdown voltage of more than 200 V and respectively occupy an area of 0.52 mm2 and 0.39 mm2. The charge pumps can output up to 182.5 V and 181.7 V and are designed to drive a capacitive load with a leakage of 2 nA. When driven with a 100 kHz clock, their power consumption is respectively 40 µW and 20 µW. The rise time of the charge pumps output from 0 V to 182 V is less than 5 ms. The implemented charge pumps exhibit state-of-the-art performance for very high voltage dc-dc capacitive drive applications.

“…In modern mobile and handheld devices, certain components require a high voltage input in order to operate. Standard boost DC-DC converters provide one method for high voltage generation but have a large footprint since they require inductors [1]. The charge pump circuit is a popular circuit topology that utilizes switches and capacitors to convert a low supply voltage to a high DC voltage output allowing for integration on silicon [2].…”

This paper proposes a multi-phase charge pump for high voltage output applications. The simple topology combines a voltage doubler with an inverting charge pump that are paralleled to provide an output voltage that is three times the input voltage. The operation of the proposed topology and the effects of multi-phasing and varying duty cycle on the input current ripple, output voltage and current ripple as well as total harmonic distortion are analyzed using LTSpice simulation. Benefits and issues from the proposed configuration will also be discussed.
