Abstract
A low power, high speed D type flip flop is disclosed. The D type flip flop uses four inverters and four transmission gates to store and output the data states. The flip flop comprises two memory elements wherein each memory element is made up of a transmission gate and two inverters. Each of the four inverters contained in the flip flop is referred to as a bypass current limiting inverter. Each of the four inverters contains biasing circuitry to limit current flow and thereby save power. Additionally, each inverter has switching circuitry that enables the current limiting features to be automatically and advantageously bypassed thereby allowing for large currents and fast response times whilst simultaneously retaining the low power performance.
