In this paper an analytical procedure to design the single-opamp active-RC Rauch
biquadratic cells is presented. The design procedure optimizes the trade-off between the
opamp input referred noise and the thermal noise due to the filter resistors, in order to
minimize the current consumption. The proposed procedure is validated by means of a
benchmark of a biquadratic cell for an UMTS and WLAN applications. The design is realized
using the 0.13 μm CMOS technology with a 1.2 V supply voltage.
