(A) - sketch a 4bit R-2R ladder digital to analog converter with reference voltage,Vref=10. by using thevenin theorem,derive the expression of Vout when MSB only turn 'on',LSB only turn 'on' and for an input B3B2B1B0 = 1010 and general expression for Vout
(B) -- based on question (A) calculate Vout using the data in the table below
Parameter | Value |
Vref | 15 V |
Rf | 100 K ohm |
R | 5 k ohm |
B3B2B1B0 | 1011 |
