Abstract
A current-sensing static amplifier-based flip-flop is useful for high-performance VLSI circuitry. The flip-flop has a short latency and a small hold time, advantageous features in high-performance microprocessors. A flip-flop circuit includes an amplifier stage and a static stage. The amplifier stage has a data input terminal and a clock input terminal. The amplifier stage includes a dual-output amplifier having two output lines connected respectively to two current pulldown paths and a gate connected between the current pulldown paths. The static stage is connected to the amplifier stage and including a static latch.
