WebAug 1, 2014 · It has been observed that the peak power efficiency of a Dickson charge pump depends mainly on the equivalent parasitic capacitance of a given technology and its operation mode, which is governed by the choices of the coupling capacitance, on-resistance of the switch, as well as the operation frequency of the circuit. Introduction
WebThe Dickson charge pump, or Dickson multiplier, consists of a cascade of diode/capacitor cells with the bottom plate of each capacitor driven by a clock pulse train. [p 7] The circuit is a modification of the Cockcroft-Walton multiplier but takes a DC input with the clock trains providing the switching signal instead of the AC input. WebApr 11, 2024 · Although the Dickson CP is simple and allows an adequate current drivability, its efficiency and voltage gain are strongly affected by the transistor threshold voltage, as can be observed in Equation (1). In general, the CTS is constituted by one or two main transistors, acting as a switch, and whose gates are properly driven by the …
