How do I know if which leg is the emitter or the collector? (Transistor . . . Off the cuff - for jellybean transistors I almost invariably use BC337 (NPN) and BC327 (PNP) - both CBE A transistor selector book woul;d be the easy way to check distributions as they have pinout tables which they assign a letter code to and then show the relevant code for each device
BJT high frequency analysis - Electrical Engineering Stack Exchange From what I remember, the Cbe depends on the emitter current Higher current causes lower reac (1 gm); at 1mA, its 26 ohms at 2mA its 13 ohms 2mA is 4 volts 2Kohm (ignoring the emitter bypass cap) Thus your circuit has an incremental emitter-base small-signal resistance of about 13 ohms If the 2N2222 has 160MHz Ftau, the emitter-base needs 1nanosecond time-constant, or 1,000 picoSeconds
Same transistor type, swapped emitter and collectors? Normal? But there are two different pinouts for the P2N2222A (a CBE pinout) and the PN2222 (EBC pinout ) So at least given my BC547 ignorance it seems at least possible in concept that other devices may have varying pinouts as I already know one example where it happens
How exactly does CPU set C BE lines on a PCI bus? The CPU cannot directly control those pins Those pins are driven by whatever device is the current bus master, which could be a PCI switch port or PCI device In the case of an operation initiated by the CPU, this will be a PCI port on some sort of bridge chip A bridge chip essentially performs a protocol translation The bits will be set based on the type of operation that the CPU performs
Radio transmitter using a crystal oscilliator I am on a mission to control my RC car using a Arduino The simplest way I thought of doing this is to add Arduino outputs into the transmitter Long story short I wanted to learn more about how th
