Voltage references are a ubiquitous function in most analog and analog-digital mixed signal designs. In most cases they need not be excessively tightly specified. A very practical voltage reference with good characteristics is the Brokaw`reference named after its inventor Paul Brokaw. It a versatile reference and quite popular. Recently Signal Processing Group Inc., released a detailed report on the complete design and layout of a Brokaw`reference in BiCMOS.
