1. A pulse generator, comprising:
- a first stage configured to be powered by a first voltage; and
a second stage configured to be powered by a second voltage different from the first voltage, wherein the second stage is further configured to generate a pulse in response to an input to the first stage comprising a trigger and feedback from the second stage, wherein the pulse transitions from a first state to a second state in response to an edge of the trigger and then transitions from the second state to the first state in response to the same edge of the trigger before a subsequent edge of the trigger occurs.
