2.3 NFET With Charge Pump

Some manufacturers offer N-channel signal switches with charge-pump-enabled pass transistors. A design of this type as shown in Figure 2-5 allows the gate voltage to be higher than VCC. This increases VGS above what is possible in noncharge-pump devices and allows signals at or above VCC to be passed. A switch of this type has the advantage of low, relatively flat RON (over the signal range), without the addition of a P channel and while maintaining Cio values comparable to pure N-channel FET switches. This performance comes at the expense of increased ICC (from a few µA to several mA in some cases). Examples include TMUX1072, TMUX136, TMUX15xx, and the CB3Q family.
