A semiconductor device includes an external resistor for establishing a delay of a signal relative to another signal in the device. The resistor may be external to a buffer, such as a zero-delay buffer, that receives an input signal generates one or more output signals that relate to the input signal. The delay may be introduced either before or after the buffer.

Signal timing adjustment circuit with external resistor

Apparatus and methods for controlling the frequency spectrum of a clock signal, for example, to reduce EMI emissions. A PLL circuit receives a reference signal and generates an output clock signal. A modulating circuit is coupled to the PLL and generates a modulating signal. The PLL receives the modulating signal and accordingly varies the frequency spectrum of the output clock signal.
