<p>For compensating the Early effect a band gap reference voltage source includes current mirror circuits (T4, Q3 and T1, Q2 as well as T2, Q1) to ensure that the currents necessary for achieving the temperature-compensated output voltage are generated. Using the current mirror circuits makes the reference voltage source independent of changes in the supply voltage (Ucc) and enables it in particular to be employed at supply voltages as of 3 V. <IMAGE></p> |
