A bipolar current-to-current convertor (CCCS) using a PNP-NPN translinear loop and two current mirrors is described. This convertor has a virtual earth input, and may be used to realise voltage-current conversion (VCCS). This convertor configuration enables us to obtain a wideband frequency response. The characteristics of a practical current source are presented.
