thanks :smile:

large signal current gain hFE = (IC - ICBO)/(IB + ICBO) and small signal current gain hfe = IC/IB 1. what is the difference between these two. 2. why can't we use large signal current gain in small signal currents?? 3. i have these notes on page 57 (page 1 on pdf) paragraph 2 of these...

I have just started studying about semiconductors. Im really confused about all these things. :confused: and i am trying very hard to get basics of junction :smile: will try to get SM Sze from library.. thanks :smile:

ok thank u :smile:

thnks a lot man... :D also please can u tell me any role of capacitance in diode.. i mean when they come into play or when their effect is seen...

A pn junction diode is driven by a voltage +E to -E volts preodically when voltage is +E its forward biases and vice versa. when in forward biased a current I flows through it, now if voltage is reversed to -E, current is still I (in reverse direction). This then stay constant for a time...
