300 V integrated charge pump for lab on chip applications

In this paper we demonstrate a fully integrated 300 V low current charge pump design which has been manufactured using Teledyne DALSA's triple well 800 nm high voltage IC process. This charge pump is powered by a 5 V supply, drawing less than 2% of the USB 2.0 maximum current, thus enabling future low-cost compact point-of-care diagnostic devices that would be connected to and powered off a laptop or smart phone. We have demonstrated this device to be capable of producing 300 V while sourcing up to 10 µA.
