Nettet23. jun. 2024 · A voltage controlled current source is a very useful circuit building block, and the Howland current source is a good example. Devised by Professor Bradford Howland at MIT in the early 1960s, it is capable of both sourcing and sinking current proportional to an input voltage. It is sometimes also called a Howland current pump.
