WebMar 17, 2015 · This may cause clipping distortions of the output signal when the follower is ac-coupled to a resistive load, for reasons which are sometimes not obvious. First, look at the simple NPN emitter ... WebA long-tailed pair (LTP), or emitter coupled (source coupled) pair, is a pair of transistors where the shared emitter or source node is supplied from a more or less constant current source/sink, which could be as simple as a …

(Collector-coupled and Emitter-coupled) using transistors, Analysis and design of Astable multivibrator (Collector coupled and Emitter- In electronics, emitter-coupled logic (ECL) is a high-speed integrated circuit bipolar transistor logic family. ECL uses an overdriven bipolar junction transistor (BJT) differential amplifier with single-ended input and limited emitter current to avoid the saturated (fully on) region of operation and its slow turn-off … See more ECL was invented in August 1956 at IBM by Hannon S. Yourke. Originally called current-steering logic, it was used in the Stretch, IBM 7090, and IBM 7094 computers. The logic was also called a current-mode … See more The ECL circuit operation is considered below with assumption that the input voltage is applied to T1 base, while T2 input is unused or a logical "0" is applied. During the transition, … See more ECL circuits usually operate with negative power supplies (positive end of the supply is connected to ground). Other logic families ground the … See more • Motorola MECL logic family datasheets, 1963 See more ECL is based on an emitter-coupled (long-tailed) pair, shaded red in the figure on the right. The left half of the pair (shaded yellow) consists of two parallel-connected input transistors T1 and T2 (an exemplary two-input gate is considered) implementing NOR … See more Other noteworthy characteristics of the ECL family include the fact that the large current requirement is approximately constant, and does not depend significantly on the … See more • Savard, John J.
