The delay circuit, such as a clock circuit, of an integrated circuit operates with tolerance of variation in temperature. For example, the delay circuit has a temperature dependent current generator that has an adjustable temperature coefficient, such that a range of temperature coefficients is selectable at a particular current output. Also, the clock circuit of an integrated circuit operates with multiple versions of a current that controls a discharging rate and/or a charging rate between reference signals of timing circuitry.
