A Low Power CMOS Mized-Integrator-Based Continuous-Time Filter

摘要：

a new Mixed-Integrator-Based bi-quad cell is presented. An alternative synthesis mechanism of complex poles is proposed comparing to source-follower-based bi quad cells which is designed applying positive feedback technique. Using negative feedback technique to combine different integrator,the proposed bi-quad cell synthesizes complex poles for designing continuous-time filter.It exhibits various advantages including compact structure,high gain, no parasitic pole,absence CMFB circuit,and high capability. An example the 4th -order Butterworth lowpass filter using the proposed cell has been designed in 0.18μm CMOS technology. The active area occupied by the filter with test buffer is only 200×170μm. The presented filter consumes low power 201μW and achieves a 52.1 dB dynamic range.
