Abstract
A biasing circuit comprising a first circuit and a second circuit. The first circuit may be configured to generate a first bias signal and a second bias signal. The second bias signal may be defined by a threshold voltage and a first resistance. The second circuit may be configured to generate a third bias signal in response to the first and the second bias signals and a second resistance. The third bias signal may have a magnitude that is linearly proportional to absolute temperature (PTAT) and be configured to vary a refresh rate of a memory cell in response to changes in temperature.
