ABSTRACT:
A BiCMOS current source reference network which eliminates the impact of d.c. power supply voltage drops on the operation of ECL circuits is described. This invention is essential for implementing ECL design techniques in VLSI BiCMOS circuits. Using the current source network, reference voltages are generated locally so that the ECL voltage references are correctly referenced to the local power supply potentials. A power supply insensitive band-gap reference generator is used to generate precision on-chip voltage references and current sources. The band-gap circuit uses both MOS and bipolar transistors and is much simpler than a similar using bipolar-only circuitry.
