**micro current pulse**. The basic structure is current mirror. When there is a current input, there is a current output, which is the exactly mirror or multiple of the input current. For I use both NMOS and PMOS to generate sink and source current.

The amplitude of the current is

**micro A**and the duration of the pulse is

**micro sec**, so I think it might be some

**special requests**for the discrete MOSFET. Could U give me some key parameters and types of discrete MOSFET for using in micro current design?

Thanks and looking forward
