A CMOS controllable constant power generator based on multiplier/divider circuit is presented. It generates constant power for a\nwide range of the resistive loads. For the generated power of 5mW, and the resistance range from 0.5 k�© to 1.5 k�©, the relative error\nof dissipated power is less than 0.6%. For single supply voltage of 5V, presented controllable constant power generator generates\npower from 0.5mWto 7.8mW, for the load resistance dynamic range from 3 up to 15, while the relative error of generated power is\nless than 2%. The frequency bandwidth of the proposed design is up to 5 MHz. Through the detailed analysis of the loop gain, it is\nshown that the circuit has no stability problems.
