Abstract :
A universal continuous-time CMOS biquad filter using novel CMOS bulk driven log-domain integrators is presented. The proposed biquad is simulated by using CMOSP 0.18-μm technology parameters offered by the Taiwan Semiconductor Manufacturing Company (TSMC) with a 1.8 V power supply, 10 KHz pole-frequency fo unity pole-quality factor Q and bias current of 3.0 nA. The total power dissipation is 20 nW/pole. Also, the sensitivity performances of the filter with respect to device mismatches are simulated in CMOSP 0.18-μm SPECTRE using the Monte Carlo analysis.
