| Summary: | This letter presents an improved, compact, and tunable high-Q differential active inductor implemented in Silterra's industry standard 0.18 µm CMOS process. The improved differential active inductor demonstrates a Q ˜ 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. |
