Abstract:
A circuit for reducing switching noise in a high speed switch, comprising:an input for receiving data signals of high and low potential;an output for delivering data signals propagated through said switch;a first terminal having a first voltage;a second terminal having a second voltage;a primary gate for switching a current path between a first state connecting said first terminal with said output and a second state connecting said second terminal with said output, and having a control terminal connected to said input for controlling the conducting state of said current path;a second gate for connecting a third voltage to said first terminal and having a control terminal connected to said input for controlling the connection of said third voltage through said second gate; anda third gate for connecting a fourth voltage to said second terminal and having a control terminal connected to said input for controlling the connection of said fourth voltage through said third gate;wherein transition of said input from low to high data signals causes said second gate switches to momentarily connect said output to said third terminal; andthe transition of said input from high to low data signals causes said third gate switches to momentarily connect said output to said fourth terminal; andsaid first state connects said first terminal to said output and said second state connects and second terminal to said output.
