A feedback mechanism to reduce current variation observed in a current reference branch circuit by using body voltage control to compensate process, temperature and supply voltage variations. The current reference output voltage, which is proportional to the reference current, is sampled into a feedback loop, which controls the field effect transistor body voltage. The method and mechanism uses Corner Robust Current Reference in order to keep the design simple and diminish variation between Process Voltage Temperature (PVT) corners. This method exhibits small variation in the reference current magnitude.
