Gyrator-Based Synthesis of Active On-Chip Inductances.

A detailed analysis of a gyrator-based inductance using operational transconductance amplifiers is presented. The advantages of such integrated inductances over passive spirals include higher quality factors and the ability to tune inductance values. Design equations are derived using a practical high-frequency model of each transconductor, and operating constraints are provided to mitigate the effects of parasitics and to ensure optimal performance and stability.
