可変制御電圧を有するスイッチ

Title:

可変制御電圧を有するスイッチ

Document Type and Number:

Japanese Patent JP2013501408

Kind Code:

A

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.
