| description | <p/> <p>We present a new analog circuit exhibiting high bandwidth and low distortion, specially designed for signal correlation in an ultra-wideband receiver front end. The ultra-wideband short impulse signals are correlated with a local pulse template by the correlator. A comparator then samples the output for signal detection. A typical Gilbert mixer core is adopted for multiplication of broadband signals up to <inline-formula><graphic file="1687-6180-2005-546896-i1.gif"/></inline-formula>. As a result of synchronization of the received signal and the local template, the output voltage level after integration and sampling can reach up to <inline-formula><graphic file="1687-6180-2005-546896-i2.gif"/></inline-formula>, which is sufficient for detection by the comparator. The circuit dissipates about <inline-formula><graphic file="1687-6180-2005-546896-i3.gif"/></inline-formula> from double voltage supplies of <inline-formula><graphic file="1687-6180-2005-546896-i4.gif"/></inline-formula> and <inline-formula><graphic file="1687-6180-2005-546896-i5.gif"/></inline-formula> using <inline-formula><graphic file="1687-6180-2005-546896-i6.gif"/></inline-formula> SiGe BiCMOS technology. Simulation results are presented to show the feasibility of this circuit design for use in ultra-wideband receivers.</p> |
