ABSTRACT:
A latch system used for providing a negative resistance. It includes a current source module used for providing at least one DC current. The latch system also includes a first cross-coupling module, which contains a first inverter, a second inverter, and an action module. The action module contains at least one action block, each of which contains a first device and a second device. The action module is electrically connected to the first and second inverter and is used for increasing the negative resistance of the latch system.
