  • High frequency voltage supply monitor
    Patent number: 9568511
    Abstract: Various aspects provide a high frequency voltage supply monitor capable of monitoring high frequency variations of the voltage supply inside a microelectronic circuit substantially in real time. The voltage supply monitor can comprise a differential amplifier circuit having a substantially constant gain over a wide bandwidth, allowing the supply voltage variations to be amplified according to a known gain under a wide range of conditions. The amplified signal can then be sent to an output port for monitoring and measurement by an external display device.
