A Single Ended Push–Pull (SEPP, SRPP or mu-follower [10]) output stage, originally called the Series-Balanced amplifier (US patent 2,310,342, Feb 1943). is similar to a totem-pole arrangement for transistors in that two devices are in series between the power supply rails, but the input drive goes only to one of the devices, the bottom one of ...
To solve the problem with the high output resistance of the simple output stage the second schematic adds to this a "totem-pole" ("push–pull") output. It consists of the two n-p-n transistors V 3 and V 4 , the "lifting" diode V 5 and the current-limiting resistor R 3 (see the figure on the right).
There is no valve analog of the complementary devices widely used in "totem pole" output stages of silicon circuits. Push-pull valve topologies therefore require a phase splitter . The very high output impedance of valves (compared with transistors) usually requires matching transformers to drive low impedance loads such as loudspeakers or ...
Open outputs configurations thus differ from push–pull outputs, which use a pair of transistors to output a specific voltage or current. These open outputs configurations are often used for digital applications when the transistor acts as a switch , to allow for logic-level conversion, wired-logic connections , and line sharing.
Archaeological investigations, carried out just 100 metres north of Stonehenge back in the 1960s suggest that a series of giant totem-pole-like timber obelisks had been erected there some 5,500 ...
A totem pole is an Indigenous, Native American artifact. Totem pole may refer to: Ed Galloway's Totem Pole Park, in Rogers County, Oklahoma; Totem pole output, also known as a push-pull output, a type of electronic circuit; The Totem Pole (Tasmania), a rock spire/sea stack in Tasmania, Australia
