Biquad Infinite Impulse Response Filter Using High Efficiency Charge Recovery Logic

Infinite Impulse Response (IIR) test-chip that has been designed using a novel chargerecovery logic family, called Enhanced Boost Logic (EBL), to achieve high-speed and low-power operation. EBL achieves increased gate overdrive, resulting in low latency overhead over static CMOS design. The test-chip has been fabricated in a 0.13 m CMOS process with a fullyintegrated 3 nH inductor. The biquad filter has the 2nd order filter design in the poles of 2. Optimized for performance and density, fully Paramerized consists of the frequency range is 365–600 MHz. It provides the resonant frequency range is 450 MHz, the test-chip dissipates 40.1 mW with a power 90.6 nW /MHz/Tap/In Bit/Coeff Bit ..
