Abstract  Static charge standard source use precision programmable voltage source and precision capacitor to produce high-precision static charge output, use negative feedback voltage automatically adjust to overcome the load capacitance and output voltage impact on the output charge amount to achieve the steady-constant output static charge, which is easy to verify the electrometers and charge amplifiers. The steady-state of this quasi-standard charge source has increased by 5 orders of magnitude over the traditional charge source. The static charge range of the standard source is 200pC~2μC, permissible error is 0.1%Qx+0.1pC, and equivalent source capacitor is 10-15F.
