CMOS spiral inductors have found a broad range of applications in highspeed analog signal processing and data communications. These applications
include bandwidth enhancement, delay reduction, impedance matching, frequency selection, distributed amplifiers, RF phase shifters, low-noise amplifiers, and voltage-controlled oscillators, to name a few. The effectiveness of these inductors, however, is affected by a number of limitations intrinsic to the spiral layout of the inductors. These limitations include a low quality factor, a low self-resonant frequency, a small and non-tunable inductance, and the need for a prohibitively large silicon area. The use of CMOS spiral transformers in RF applications such as low-noise amplifiers, power amplifiers, and LC oscillators has emerged recently. These transformers are constructed by coupling two spiral inductors via a magnetic link. They offer the advantages of a reduced silicon consumption and increased inductances. The limitations of spiral inductors, however, are inherited by spiral transformers.

Inductors and transformers synthesized using active devices, known as active inductors and transformers, offer a number of unique advantages over their spiral counterparts including virtually no chip area requirement, large and tunable inductances with large inductance tuning ranges, large and tunable quality factors, high self-resonant frequencies, and full compatibility with digital oriented CMOS technologies. Active inductors and transformers have found increasing applications in high-speed analog signal processing and data communications where spiral inductors and transformers are usually employed. As compared with spiral inductors and transformers, the applications of CMOS active inductors and transformers are affected by a number of limitations intrinsic to synthesized devices. These limitations include a small dynamic range, poor noise performance, a high level of power consumption, and a high sensitivity to supply voltage fluctuation and process variation.
