“…The component-matching problems of the latter filter are also absent. The direct-tuning tech nique is o f advantage in RF high-Q LC filters since use can be made of the same ADC and other digital circuitry that are used for demodulating the signal [37]. A disadvantage o f direct tuning is that the filter needs to be switched between normal filter and tuning modes.…”

“…The major issues in such receivers are noise-folding, sensitivity to clock jitter and linearity requirement. Noise folding can be reduced by using a narrow band pre-select filter [36,37,38].…”

“…On a side note, it is interesting to see that "only" across a limited bandwidth, tuning to a higher a> 0 requires reducing the tank capacitance and the effective load transconductance, G p -G q , by the same rate, in order to keep the bandwidth constant 38 . This is shown as follows…”
