<p>A bias circuit which tracks the gain and operating characteristics of other transistors in an integrated circuit. The bias circuit employs the bandgap reference voltage, VCS, as the power source. By a transistor (26) and resistor network (24, 28, 29) a bias circuit voltage (VCSL) is generated. The bias circuit is useful in providing a bias to the base (e) of a dynamically switchable low drop current source (33) useful in ECL circuits.</p> |
