Language translation: Deutsch:.This invention relates generally to a device for converting an analog input signal into a binary output signal having an output signal level that is related to the amplitude of the input signal.
The design of bipolar digital circuits requires a high degree of analog to digital conversion (ADC) or a high degree of digital to analog conversion (DAC) in order to perform a large number of digital logic functions in a single integrated circuit. With such functions, it is desirable to develop a simple and inexpensive ADC and DAC, since it is usually necessary to provide a multiplicity of such ADCs and DACs on a single integrated circuit. One approach in designing such an ADC and DAC is to utilize a sample and hold circuit which converts an analog input signal into a single time sample of its amplitude. Then, the amplitude of the input signal is related to the amplitude of the output signal by an effective gain which is dependent upon the integration of the digital output signal that is produced by the sample and hold circuit. Therefore, if the effective gain is set too high, it would require an ADC with an unnecessarily large number of bits to convert an analog signal that was not so great.
An alternative approach to the design of an ADC and DAC is to convert an analog input signal into a plurality of sample values and use a comparator circuit to compare the input signal to each sample value to produce a digital output signal. By using a number of samples that is larger than the number of input bits needed to represent the analog signal, a multi-level analog to digital conversion result is obtained. The comparator circuit may include a number of storage locations which are used to hold the sample values, and a digital logic circuit having a digital output stage which provides a digital output signal representing the amplitude of the input analog signal. For example, if the digital output signal has five logic levels, the input analog signal can be divided into five levels by the comparator circuit. While the multi-level analog to digital conversion operation is theoretically possible, the complexity of such circuit becomes overly expensive for the conversion of small analog signals. Therefore, the use of a multi-level ADC is limited to the conversion of large amplitude signals.Q:
