Beschreibung
- High-side voltage-to-current (V-I) converter. This high-side voltage-to-current (V-I) converter delivers a well-regulated current to a ground referenced load. The design utilizes a two-stage approach to allow the high-side current source to accept a ground-referenced input. The first stage uses an Op-Amp and n-channel MOSFET to translate the ground-referenced input to a supply-referenced signal. The supply-referenced signal drives the second stage Op-Amp that controls the gate of a p-channel MOSFET to regulate the load current
