Abstract: Techniques for detecting jammer signals in a received signal are described. In one aspect, high-speed current mirror resistive compensation circuits and output impedance boosting circuits are utilized to increase amplifier bandwidth in an improved wideband amplifier circuit. In another aspect, a dual transistor configuration including common source topology, averaging capacitors and a comparator circuit is utilized to improve the sensing of signal peaks in a peak detector block, which can be used together with the wideband amplifier circuit and a digital jammer detection circuit to detect jammer signals. The digital jammer detection circuit aids in the determination of the presence of jammer signals within the received signal, the determination of which may be variable due to programmability of the digital jammer detection circuit as described.
