Abstract:
1. An electrical circuit comprising: a power supply system sub-circuit (PSSC) having a dynamic voltage controlled decoupling capacitor connected to a power supply that generates a power supply voltage, wherein the PSSC further comprises a switching current supply connecting a gate node and a source node of the dynamic voltage controlled decoupling capacitor and the power supply, wherein the power supply, dynamic voltage controlled decoupling capacitor, and switching current supply are connected in parallel; and a voltage sensor sub-circuit (VSSC) that detects a voltage variation within the power supply voltage that is causing a varying voltage level of the power supply voltage and generates a control voltage that is directly applied to a drain node of the dynamic voltage controlled decoupling capacitor to compensate for the voltage variation and reduce a level of noise in the power supply voltage, wherein the voltage variation is caused by one or more switching currents within the power supply.
