Modern SIM cards allow applications to be loaded when the SIM is in use by the subscriber. These applications communicate with the handset or a server using SIM application toolkit, which was initially specified by 3GPP in TS 11.14 (there is an identical ETSI specification with different numbering).
(Redirected from Voltage follower) A buffer amplifier (sometimes simply called a buffer) is one that provides electrical impedance transformation from one circuit to another. Two main types of buffer exist: the voltage buffer and the current buffer.
What is FORWARD-BIAS? Said of a semiconductor diode, p-n junction, or the emitter-base junction of a transistor, when the polarity of the applied emf is such as to allow substantial conduction to take place, TRANSISTOR.
