摘要： An active clamp circuit for electronic components includes two sets of diode connected transistors that are inversely connected in parallel across an output of the component for providing both positive and negative differential conducting paths. The diode connected transistors cooperatively operate to limit a differential output voltage between the positive and negative conducting paths. An emitter follower buffer includes the clamp circuit and is configured to limit RF energy incident to an analog to digital converter (ADC). The emitter follower buffer includes two input transistors having their emitters each connected to at least one diode connected transistor connected to the clamp circuit. A receiver includes the differential amplifier and an analog to digital converter. A method for limiting the energy of analog signals in the receiver includes the step of operating the clamp circuit to limit the analog signals transmitted to the analog to digital converter (ADC).
