SWITCHES WITH VARIABLE CONTROL VOLTAGES
First Claim
1. An apparatus comprising:
- a switch to receive an input signal at one terminal and is turned off;
a peak voltage detector to detect a peak voltage of the input signal; and
a control voltage generator to generate a variable control voltage to turn off the switch based on the detected peak voltage.

Abstract
Switches with variable control voltages and having improved reliability and performance are described. In an exemplary design, an apparatus includes a switch, a peak voltage detector, and a control voltage generator. The switch may be implemented with stacked transistors. The peak voltage detector detects a peak voltage of an input signal provided to the switch. In an exemplary design, the control voltage generator generates a variable control voltage to turn off the switch based on the detected peak voltage. In another exemplary design, the control voltage generator generates a variable control voltage to turn on the switch based on the detected peak voltage. In yet another exemplary design, the control voltage generator generates a control voltage to turn on the switch and attenuate the input signal when the peak voltage exceeds a high threshold.
