Patent ID: 7129752

Claim:
An integrated circuit device comprising: a first circuit part biased from a lower voltage supply VCC_LOW; a second circuit part biased from a higher voltage supply VCC_UPP; at least one of the first and second circuit parts having an RS flip-flop I 2 , I 3 with complementary signal outputs, and the other of said first and second circuit parts having a signal input IN; a first switching transistor M 1 with a gate connected to the signal input IN and a second switching transistor M 2 with a gate connected to the signal input IN through an inverter I 1 ; the first and second switching transistors each having a current channel DC coupled in series with a respective cascode-connected transistor connected to a respective one of the signal outputs, one of said outputs being coupled with said input through a first feed-forward AC series circuit of an inverter I 4 and a first coupling capacitor C 1 , and the other of said outputs being coupled with said signal input IN through a second feed-forward AC circuit including a second coupling capacitor C 2 .
