A bipolar transistor can be used as the simplest current-to-current converter but its transfer ratio would highly depend on temperature variations, β tolerances, etc. To eliminate these undesired disturbances, a current mirror is composed of two cascaded current-to-voltage and voltage-to-current converters placed at the same conditions and having reverse characteristics. It is not obligatory for the… Webtion of the current mirror’s current normalized to expected value of 1/200 of I DS. I CM current lost linearity immediately after interception point at I DS = -17 A. Utilization of the ICM raises up to 1 immediately after that point and falls fast after that to the level determined mostly by a body diode. Using current mirror’s current at I
