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.
VCEsat The collector emitter saturation voltage, i.e. the voltage across the transistor (collector to emitter) when the transistor is turned hard on. It is normally quoted for a particular base and collector current values.Hfe.
