AN-1515 A Comprehensive Study of the Howland Current Pump (Rev. A)
PDF, 165 Kb, 修订版: A, 档案已发布: Apr 26, 2013
It is well known to analog experts that you can use the positive and negative inputs of an operationalamplifier to make a high-impedance current source (current pump) using a conventional operationalamplifier (op amp). This basic circuit can put out both + and - output current (or zero current) into variousloads. The theory is simple. But the practical problems involved are not so simple or
