ABSTRACT:
Propagation delay along a signal path in a programmable logic device is reduced by providing improved switching and buffering along the device signal path. Such improvement is achieved by providing a separate buffer for each signal path leading from a given device input pad. In this manner, the buffer is smaller without increasing net power consumption. Improved output drivers are also provided in which device sizes are optimized to sink/source larger amounts of current, thereby improving device speed. A feedback arrangement, including a bootstrap device, provides a path that augments the current provided within the output buffer, thereby assisting a low to high signal transition. An improved OR gate is also provided that precharges a gate output line to ensure fast state transition, while eliminating the need for complementary gate switching logic.
