CPC H03K 3/011 (2013.01) [H03F 3/45475 (2013.01)] | 20 Claims |
1. A semiconductor device comprising:
a temperature-independent current generator configured to generate a reference current substantially independent of temperature and a first mirror current, a second mirror current, and a third mirror current that are substantial duplicates of the reference current;
a first pulse signal generator coupled to the temperature-independent current generator and configured to sample the first mirror current so as to generate a pulse signal;
a first counter coupled to the first pulse signal generator and configured to obtain a number of pulse signals generated by the first pulse signal generator, to permit the first pulse signal generator to generate a pulse signal when it is determined thereby that the number of pulse signals obtained thereby is less than a predetermined threshold value, and to inhibit the first pulse signal generator from generating a pulse signal when it is determined thereby that the number of pulse signals obtained thereby is equal to the predetermined threshold value; and
a temperature-dependent current generator configured to receive the second mirror current and the third mirror current generated by the temperature-independent current generator and to generate a temperature-dependent current based on the second mirror current and the third mirror current received thereby.
