Description
Summary:This letter presents an improved, compact, and tunable high-@@iQ@ differential active inductor implemented in Silterraas industry standard 0.18 mum CMOS process. The improved differential active inductor demonstrates a @@iQ@ ap 1000 at high frequency region. Low-current dissipation is achieved by reusing the current from the differential gyrator for stabilizer and negative impedance circuit. A replica bias circuit has been introduced to allow current-controlled inductance of the improved differential active inductor. Sensitivity of the improved differential active inductor to process variation is also included in this letter.
