1.
A) An 8-bit ADC with a reference voltage of
5V is implemented using the Counter
Ramp technique. Assume the input voltage
is 1.4V. How many clocks are needed
to conduct a conversion? You do not need
consider the sampling time.
B) A 10-bit ADC with a reference voltage of
5V is implemented using the SAR
technique. Assume the input voltage is 3.2V.
How many clocks are needed to
conduct a conversion? You do not need
consider the sampling time.
C) An analog signal has a maximum
frequency of 300HZ, what should be the
minimum sampling rate of the ADC so that
the digitized data can be used to
perfectly reconstruct the original analog
signal?
D) For an 8-bit DAC, if Vref = 6 V, and the
input code is 0×4B (01001011), what is
the DAC output voltage?
E) A 8-bit ADC has a reference voltage of
6V. What is the max quantization error?
