A method and apparatus for determining a data storage bit width and a method for storing exponential data. The method for determining the data storage bit width includes: acquiring data to be stored, the number of which is at least 4; dividing the data into blocks according to a preset number 2, n is an integer greater than or equal to 2; determining effective bit numbers and a value of a maximum effective bit number in a block; dividing data in the block equally into a first sub-block and a second sub-block, acquiring effective bit numbers in first and second sub-blocks; performing a differential calculation on effective bit numbers in first and second sub-blocks to obtain an effective differential value; determining a storage bit width for storing effective differential value according to a preset storage bit width interval to which the value of maximum effective bit number belongs.

A semiconductor integrated circuit (IC) acts as a controller of a heating-controlled device or appliance. A heating body has a positive temperature coefficient and acts as both a heating element and a temperature sensor. A Silicon-Controlled Rectifier (SCR) switches AC current to the heating body to increase its temperature. When the SCR switches off, temperature sensing is performed using a sampling resistor, isolation diode, voltage comparator, and switch for a low-voltage DC supply are formed on an integrated circuit that has a first circuit branch and a second circuit branch. A compensation diode and a compensation resistor can be added in parallel to reference resistors. The compensation diode compensates for the forward voltage drop of the isolation diode that would otherwise create an inaccurate temperature measurement. The diodes have the same temperature response, allowing for a more accurate temperature measurement over a full temperature range of the sensorless appliance.
