Patent ID: 11949382
Assignee: CIRRUS LOGIC INC.
Field: Basic communication processes (Electrical engineering)
Classification: CPC H | IPC H

Claim 0:
1. Circuitry comprising:
amplifier circuitry for driving a load;
boost circuitry for supplying a variable supply voltage to the amplifier circuitry; and
processing circuitry configured to:
monitor a voltage monitor signal (VMON) indicative of a voltage across the load when driven by the amplifier circuitry and/or a current monitor (IMON) signal indicative of a current through the load when driven by the amplifier circuitry;
determine a level of electrical coupling between the boost circuitry and the voltage monitor (VMON) and/or current monitor (IMON) signals; and
apply a correction to the voltage monitor (VMON) and/or current monitor (IMON) signals based on the determined level of coupling.
