Abstract
A circuit comprises a control line and a two terminal semiconductor device having a first terminal is coupled to a signal line, and a second terminal coupled to the control line. The semiconductor device has a capacitance when a voltage on the first terminal is above a threshold and has a smaller capacitance when a voltage on the first terminal is below the threshold. A signal is placed on the signal line and a voltage on the control line is modified. When the signal falls below the threshold, the semiconductor device acts as a very small capacitor and the output will be a small value. When the signal is above the threshold, the semiconductor device acts as a large capacitor and the output will be influenced by the signal and the modified voltage on the control line and the signal is amplified.
