摘要
A digital temperature detecting system for detecting a working temperature of a chip. The digital temperature detecting system includes a clock generator, for generating a first clock signal having a constant frequency; an oscillating circuit having a plurality of Not gates coupled in series, for generating a second clock signal, wherein a total number of the Not gates is an odd number; a command issuing unit connected to the clock generator, for generating a reference command signal according to the first clock signal, wherein a counting duration and a recovery duration are generated periodically in the reference command signal; and a command processing unit connected to the command issuing unit and the oscillating circuit, for generating a counting number through counting the clocks generated in the second clock signal in the counting duration and determining a working temperature according to the counting number.
