Design to Introduce On-chip Fine Tunability in Analog Active Inductor

This work presents fine tunability in simple single ended active inductor using non-volatile, on-chip, post fabrication and indirect programming in floating gate transistor, employed as tunable feedback resistor in the design. The inductor find applications in navigation(L band:1 to 2 GHz) and in mobile telecommunication base-stations(1.8-2.1 GHz) as it generate several inductances in nH (3-7 nH) at few GHz frequencies (1-2.5 GHz) with highly precise programming resolution (about 13 bit i.e., 213 inductance values) in which, fine tunability is in priority to operating speed. It shows temperature and noise sensitivity better than the design using feedback resistor.
