Capacitance Multiplier for Decoupling Capacitor - A simplified explanation of the abstract
This abstract first appeared for US patent application 18466708 titled 'Capacitance Multiplier for Decoupling Capacitor
Simplified Explanation
The abstract describes an integrated circuit that includes capacitance multiplier circuitry. This circuitry consists of a capacitor, fixed and tunable resistances, and a transconductance circuit. The tunable resistance allows for control of the overall capacitance of the circuitry. The transconductance circuit includes a transistor that is connected to two electrical components. The capacitance multiplier circuitry provides a large adjustable amount of capacitance without voltage drop or high power consumption.

Original Abstract Submitted
An integrated circuit may include one or more circuits coupled to capacitance multiplier circuitry. The capacitance multiplier circuitry may include a capacitor, fixed and tunable resistances, and a transconductance circuit. The tunable resistance can be adjusted to control the overall capacitance of the capacitance multiplier circuitry. The transconductance circuit may include a transistor having a drain terminal coupled to a first electrical component and a source terminal coupled to a second electrical component. The first electrical component may be a diode-connected transistor, a direct shorting wire, a resistor, an inductor, or a current source. The second electrical component may be a current source, a direct shorting wire, a resistor, an inductor, or another diode-connected device. Configured in this way, the capacitance multiplier circuitry can provide a large adjustable amount of capacitance without a voltage drop and without consuming a large amount of power.
