My project needs a charge pump that can boost a fixed DC voltage (250mV or less) up to a usable DC output (around 1.8V to power an IC). Since it is energy harvesting our teacher said not to use a supply (VDD) and just purely depend on the input as source (that is the 250mV or less). I have tried using some low-power voltage doubler and it gives me a good result but the problem is that it uses a clock and making a circuit with the same input as the charge pump is hard for me. By the way, it is in 0.18um cmos technology. Anybody can help?.. Thanks in advance.
