- •
One new readout method to measure the DC value was proposed and characteristics as well as principle of the proposed method was analyzed.
- •
One Pspice model based on the proposed method was built and the correctness was confirmed by simulations performed under several conditions.
- •
Several physical sensors were implemented and the feasibility and effectiveness was confirmed by leakage current detection test.
