Abstract:
1. A semiconductor integrated circuit, comprising; a control circuit; and a power management integrated circuit (IC) configured to supply an operating voltage to the control circuit, wherein the control circuit comprises: a clock generator configured to generate a clock signal; a processor unit configured to operate in response to the clock signal and to operate the control circuit; a temperature sensor configured to sense a temperature of the control circuit to generate temperature data; a body bias generator configured to supply a body bias voltage to the processor unit; and a controller configured to receive the temperature data from the temperature sensor, wherein the controller controls the power management IC and the clock generator when the temperature data indicates a temperature higher than a high temperature and controls the power management IC or the body bias generator when the temperature data indicates a temperature lower than a low temperature; and wherein the high temperature is lower than a hot temperature of the control circuit and the low temperature is higher than a cold temperature of the control circuit and lower than the high temperature.
