Abstract
A temperature dependent clock circuit (,) is disclosed. The clock circuit (,) includes a reference circuit (,) that provides a first group of reference signals (,) with positive temperature coefficients and a second group of reference signals (,) with negative temperature coefficients. A sample circuit (,) compares the first group of signals (,) with a second group of signals (,) and provides a group of bias signals (,) representative of the operating temperature of the clock circuit (,). A frequency controllable oscillator circuit (,) provides an output clock signal (CLK) having a frequency that is dependent upon the values of the bias signals (,).
