Patent ID: 8324667

Claim:
A method for amplifying signals, the method comprising the steps of: determining that a voltage on a signal line is to be amplified; and modifying voltage on a control line, wherein the control line is coupled to a second terminal of a two terminal semiconductor device, the two terminal semiconductor device having the second terminal and a first terminal, the first terminal coupled to the signal line, the second terminal coupled to the control line, wherein the two terminal semiconductor device is adapted to have a capacitance when a voltage on the first terminal is in a first voltage range and to have a lower capacitance when the voltage on the first terminal is in a second voltage range, wherein said first and second voltage ranges are defined by a threshold voltage, and wherein the control line is adapted to be coupled to a control signal and wherein the signal line is adapted to be coupled to a signal and to be an output; and wherein an isolation device is intermediate the signal line and the two terminal semiconductor device, the isolation device having an input, an output and a control terminal, the input of the isolation device coupled to the signal line and the output of the isolation device coupled to the first terminal, wherein the output of the isolation device is adapted to be the output, and wherein the method further comprises the step of applying a control voltage to the control terminal of the isolation device, the control voltage being greater than a threshold voltage of the isolation device.
