Abstract
Embodiments of the invention provide for a dynamic pulse generator which can combine both the sequential element and the pulse logic into one stage, thereby eliminating the wasted time resulting from a pulse generator' input-to-output propagation delay. The dynamic pulse generator can include a plurality of P-MOS an N-MOS transistors, a first delay element, and a second delay element.
Claims12
A pulse generator, the pulse generator comprising:
- a first P-channel metal-oxide-semiconductor (P-MOS) transistor;
- a second P-MOS transistor;
- a first N-type metal-oxide-semiconductor (N-MOS) transistor;
- a first delay element;
- and
- a second delay element that is not the first delay element, the second delay element being a programmable delay element;
- wherein:
- the first delay element is configured to generate a delayed version of a clock pulse input;
- the second delay element is configured to generate a delayed version of a clock pulse output;
- the first P-MOS transistor includes:
- a first gate connected to an output of the first delay element, a first drain connected to a first intermediate node, and a first source connected to a first power supply;
- the second P-MOS transistor includes:
- a second gate connected to the clock pulse input, a second drain connected to the clock pulse output, and a second source connected to the first intermediate node;
- and
- the first N-MOS transistor includes:
- a third gate connected to an output of the second delay element, a third drain connected the clock pulse output;
- and a third source connected to a second power supply.
