Abstract:
An integrated circuit device comprising:a load node at which a reference voltage is generated when the device is in use;load circuitry connected to said load node for receiving therefrom said reference voltage;a reference voltage amplifier having an output whose impedance has an effective inductive component in a desired range of operating frequencies of said load circuitry;a first resistance element, having a preselected resistance, connected between said output and said load node for supplying said reference voltage to that node;a connection terminal to which external capacitance having a preselected capacitance is connected when the device is in use;a second resistance element, having a preselected resistance, connected between said load node and said connection terminal;thereby to reduce an impedance variation with frequency of the load node over said desired range of operating frequencies of the load circuitry.
