  text: An ultra-broadband analog correlator consisting of a four-quadrant multiplier
    and an ultra-fast resettable integrator using only NPN transistors was designed,
    fabricated, and measured. For the integrator, a cross-coupled transistor pair
    is used as a negative resistance generator. A novel ultra-fast reset circuit is
    implemented which allows to reset the integrator within very short time of 120
    ps. The chip was fabricated using 130 nm SiGe BiCMOS technology with fT of 250
    GHz and f max of 300 GHz. In the measurements carried out on printed circuit board,
    the correlator operated without noticeable performance degradation with inputs
    up to 33 Gbps which correspond to a bandwidth of more than 24 GHz. The correlator
    exhibits high linearity with output P1dB of more than 9.9 dBm (700 mV diff ) for
    both inputs. It dissipates 122.5 mW for the core circuit excluding the 50 Ω output
    driver. To the knowledge of the authors, the circuit represents the fastest analog
    correlator published so far. It can be used for spread spectrum communication,
    radar signal processing, and measurement applications.
