Abstract
For example, a pulse transmission circuit includes: a constant current source configured to generate a constant current; a capacitor configured to be charged using the constant current (e.g., a charge current generated by mirroring the constant current); and a discharge switch configured to pass a discharge current from the capacitor to a transformer according to a pulse edge in an input pulse signal, thereby to pulse-drive the transformer.
