Abstract
An exemplary system and method is disclosed employing a floating inverter amplifier comprising an inverter-based circuit comprising an input configured to be switchable between a floating reservoir capacitor during a first phase of operation and to a device power source during a second phase of operation. In some embodiments, the floating inverter amplifier is further configured for current reuse and dynamic bias. In other embodiments, the floating inverter amplifier is further configured with a dynamic cascode mechanism that does not need any additional bias voltage. The dynamic cascode mechanism may be used in combination with 2-step fast-settling operation to provide high-gain and high-speed noise suppression operation.
