Abstract
A device to detect an electrical signal is provided. The device includes sensing, output, and pull-down nodes. The device includes a pull-down circuit having a native metal-oxide-semiconductor field-effect transistor (MOSFET) to pull down the output node to approximately a voltage of the pull-down node. The device includes a switch circuit having a junction field-effect transistor (JFET). The JFET turns on the pull-down circuit in response to a voltage of the sensing node being less than a first threshold. The JFET also turns off the pull-down circuit in response to the voltage of the sensing node being greater than the first threshold.
