Hello everyone!
I was reading OpAmps for everyone (available here) and found something strange on page 37.
Does anyone know if the I_L they use is the current flowing through a possible load resistor (i.e. 50 ohms) connected from V-out / V_C to ground? For me what it does not make sense is that they draw IC being the current flowing through R_C and then they use a different notation in the expressions, like I_C is the sum of the current through R_C and the current through the load resistor I_L.
They also refer to Equation 2-27 when they talk about the off case, therefore V_CE is not 0 but at least 10 V.
Did I get it correctly? Doesn't it look a bit incoherent?
Thanks in advance.
