Summary :

We propose a directly controlled emitter-follower circuit with a feedback type level stabilizer for low-voltage, low-power and high-speed bipolar ECL circuits. The emitter-follower circuit employs a current source structure that compensates speed and power for various supply voltage and temperature. The feedback controlled circuit with a small current source stabilizes 'High' level. At a power consumption of 1 mW/gate, the new circuit is 45% faster under the loaded condition (FO1, CL0.5 pF) and has 47% better load driving capability than conventional ECL gates.
