Bootstrapped switch with a highly linearized resistance |
摘要 |
Systems and methods are disclosed for operating a highly linearized resistance for a switch through use of a bootstrapped features. In one exemplary implementation, there is provided a method and system that implements a method for operating a circuit configured to provide a highly linearized resistance including receiving a signal via a bootstrapped switch, coupling the received signal to a gate if the received signal is high, receiving a signal via a switch control input coupled to a high impedance element. Moreover, the method includes coupling the high impedance element to the gate and turning off the switch via a gate turn off when the gate turn off pulls the gate low. |

1. A circuit that is configured to provide a highly linearized resistance, the circuit comprising:
a switch having an input, output, and a gate wherein the switch is configured in a bootstrap configuration; a high impedance element having a first and a second terminal, the first terminal coupled to the gate, wherein the high impedance element includes at least two diodes in series, the diodes being in parallel with a resistor; a gate turn off element having a first terminal and a second terminal, the first terminal coupled to the gate and the first terminal of the high impedance element; a switch control input coupled to the second terminal of the high impedance element; and a clamping diode coupled to the gate and configured to limit the gate swing of the switch. |
