Hi all,
Microelectronic Circuits Sedra&Smith
In the beginning of chapter6 'Differential and multistage Amplifier', it explains about differential signals. The part I dont understand is that
why if VB2=0 and VB1=+1, Q2 is off and Q1 is on? and why if Vb1=-1 and VB2=0, Q2 is on and Q1 is off?
(this is on page 488 and 489)
Could anyone help me explain this?
