WebAug 18, 2024 · On the level of a PCB, currents are routinely measured using current shunts, and there's billions of those things - most switching power supplies have a shunt that measures AC current. Sometimes the shunt is cleverly integrated into a semiconductor component, e.g. it may be the channel resistance of a mosfet. WebThe upper circuit (a) uses an instrumentation amplifier (IA) powered by a separate rail (>1V above V IN) to measure across the 1kΩ current shunt. The lower figure (b) is similar but derives its power supply from the APD bias line. The limitation of these circuits is the 35V maximum APD voltage, whereas some APDs may require 90V or more.
