PURPOSE:To simplify the structure of a digital comparator and at the same time to realize a desired comparison function over a wide range, by using only two sequential RAMs and a circuit means to write data to these RAMs. CONSTITUTION:Optional number of the primary RAM1 and 2 and the ...
The comparator/voltage reference structure shown in the diagram is more of a representation of the function performed than the actual circuit used, which is much more integrated with the switching, and correspondingly harder to analyze. 6.68 CONVERTERS ANALOG-TO-DIGITAL CONVERTER ARCHITECTURES Figure ...
Reference Voltage– Provides stable voltage threshold for comparator. Set based on thermistor specs. This simple circuit can measure over a narrow range of ~50°C with 1-2°C accuracy. Wider range thermometers require additional components. LM35 Based Thermometer The LM35 linear temperature sensor ma...
Comparator circuit 5. D flip-flop and AND gate The circuit also requires a clock signal. The operation of the circuit can be described from the point in time that a start-conversion gate is applied. This signal causes the D flip-flop to set, which immediately switches the S/H circuit to...
