Abstract :
A complementary emitter follower composed of a direct-coupled npn transistor and a capacitor-coupled pnp transistor is proposed. Low power dissipation and good noise removing capability can be obtained by this coupling scheme. An ECL gate with this complementary emitter follower is 63% faster and has 4 times better load driving capability than a conventional ECL gate.
