Abstract
Disclosed are methods and systems for implementing various circuitry within a high speed, high frequency signal environment such as an integrated circuit. In one embodiment, an improved clock tree mechanism utilizes multiple low power drivers to distribute a clock signal to various load cells. In another embodiment, a single circuitry in current mode logic is used to implement a combined multiplexer, buffer and level shifter. In other embodiments, improved static and partially static flip-flop circuitry is disclosed which uses fewer devices and less power than conventional circuitry while achieving the same functionality.
Claims22
An apparatus for holding and releasing a data signal and a scan data signal, comprising:
- a feed forward mechanism accepting said data signal;
- a selection and transmission mechanism for selecting and transmitting one of said data signal and scan data signal;
- a first latch configured to accept and hold said transmitted one of said data signal and said scan data signal;
- a first driver, the input of said first driver coupled to the first latch and to said feed forward mechanism;
- a transmission gate coupled to the output of said first driver;
- a second latch coupled to the output of said transmission gate;
- and
- an output diver coupled to the output of said second latch.
