Senior Design Team sdmay20-11 • Design of a Charge Measurement Device

We are tasked by Honeywell to build a circuit that can measure the amount of charge of a connected device. This circuit will be used in a laboratory environment and will be operating in the range of 250 – 750 VDC. The measurement will be taken during the discharge between a pin and a circular connector shell. The circuit is going to need to be able to measure charges between 10 nano Coulombs and 300 nano Coulombs. The charge will be measured from the connector shell to ground. Honeywell plans to use this circuit to measure the accumulated charge for multiple pins.
