Digital Electronics 13.4b Chapter 13 33, 34, 35 Also 1. Design the details of a 4-bit Successive Approximation Converter according to the block diagram given in class (i.e. design the DAC, SAR, control logic, and latch). 2. A dual slope ADC uses a 16-bit counter and a 4MHz clock rate. The maximum input voltage is +10V. The maximum integrator output voltage should be -8V when the counter has cycled through 2n counts. The same counter is used for the charging and discharging of the capacitor. The capacitor used in the integrator is 0.1F. a) Find the value of the resistor of the integrator. b) If the analog input signal is 4.129V, find the equivalent digital output. c) What should Vref be set to?
