Flip-flop circuit with resistive poly routing

摘要

A latch circuit has a tri-state gate and a reverse tri-state gate that share the same complementary controls. The reverse tri-state gate locks an output of the tri-state gate when the tri-state gate is shut-off. The complementary control signals include a first undoped polysilicon strip. The output of the reverse tri-state gate may be coupled to the output of the tri-state gate via a second undoped polysilicon strip.

主权项

1. A latch circuit, comprising:
a tri-state gate having an input, an output, and receiving complementary control signals; a reverse tri-state gate having an input, an output, and sharing the complementary control signals with the tri-state gate, wherein the reverse tri-state gate is configured to lock an output of the tri-state gate when the tri-state gate is shut-off; a first undoped polysilicon strip for generating one of the complementary control signals; and a second undoped polysilicon strip coupled between the output of the tri-state gate and the output of the reverse tri-state gate.
