Patent attributes
A latch includes: an amplifying circuit, for receiving a first bias current in a first state for amplifying an input signal to generate an amplified signal; a latching unit, for latching the amplified signal and receiving a second bias current in a second state to output the amplified signal; and a biasing circuit, for providing a biasing current to the amplifying circuit, and providing the second biasing current to the latching unit. The biasing circuit includes: a first biasing module for providing a third biasing circuit to the amplifying circuit in the first state; and a second biasing module, for providing a fourth biasing current to the amplified circuit; wherein the first biasing circuit is equal to a sum of the third biasing current and the fourth biasing current.
