The invention discloses a temperature sensor and a temperature sensing method. The temperature sensor is equipped with an enabling end EN, a start end START and an output end Dout, wherein (1), a first output end (Iptat1) of a current source is connected with an e pole of a triode; (2), a second output end (Iptat2) of the current source is connected with a D pole of an MOS transistor, an S pole ofthe MOS transistor is grounded, and the start end START is connected with a G pole of the MOS transistor through utilization of a not gate; (3), the e pole of the triode is connected with an in-phaseinput end of a comparer, and the D pole of the MOS transistor is connected with an inverted input end of the comparer; and (4), the enabling end EN and an input end (EN) of the current source are connected with a first input end of the not gate, an output end of the comparer is connected with a second input end of the not gate, and the output end of the not gate is connected with an R end of an RS trigger. The temperature
