Abstract
A differential-slope-limiting-switch and method are provided. Generally, the switch includes a first transistor having a first source-drain (SD) and well coupled to a first port of the switch, a gate, and a second SD, and a second transistor having a first SD and well coupled to a second port, a gate, and a second SD coupled to the second SD of the first transistor. A selector-circuit couples the gate of the first transistor to a first current-source when a signal to close the switch is received, and to the first port when it is not received. A second selector-circuit couples the gate of the second transistor to a second current-source when the signal is received, or to the second port. First and second feedback-capacitors couple each gate to the port on opposite sides of the switch and with the current-sources limit a slope of voltage transitions across the closed switch.
