| Abstract: | This paper suggests a kind of circuit, named Smooth Noti-Linear A/D Co- nverter, with the feature of simplicity and better precision. It can be applied in some sensors with non-linear characteristics. In the case of sensors of Pt resistance type used, within the range of -200 C to +650C the error is less than 0.058 per centum. When CMOS.LSI of A/D Conyerter with 3 1/2 bit is used, the precision of Digital Thermometer is practiclly 0.12 per centum within the same range as above mentioned. The paper also discusses the method of selecting the parameter I, K in the circuit and suggests two programs for this selection on the microcompute PC-1500. With these programs, the optimum parameters and relevant error can be found. Finally this paper suggests a method of increasing linear precision, and the variatiotis of application are enlarged. |
