ABSTRACT:
A DC coupled amplifier fed by an RF detector is taught which has greater dynamic range capabilities than techniques in the prior art. An illustrative embodiment of the present invention advantageously comprises a low-off set voltage, low-offset current differential amplifier fed by an RF detector having a fifth lead from the reference voltage node within the RF detector.
