Abstract
A decoupling circuit comprising a first capacitor, and a first current mirror coupled to the capacitor, wherein the first current mirror is configured to multiply the capacitance effect of the first capacitor is disclosed. The first current mirror may comprise a first transistor, and a second transistor coupled to the first transistor, wherein the second transistor is configured to amplify the current entering the first transistor. The first transistor and the second transistor may comprise n-channel MOSFET transistors. The decoupling circuit may further comprise a bias network coupled to the first current mirror, wherein the bias network is configured to bias the first current mirror. The bias network may comprise a p-channel MOSFET.
