Abstract
The operation, biasing, and measured performances of the floating-body silicon-on-sapphire (SOS) MOSFET as a single-gate FET upconversion mixer are presented. Despite the floating-body effects of the SOS MOSFET, the upconversion RF mixer operation is feasible by utilizing the approximate square-law transfer characteristics of the SOS MOSFETs. With a drawn gate length Lmin = 0.8 μm, the single-gate SOS MOSFET mixer gives an approximately 1.5-dB power conversion gain, an input-referred third-order intercept point (IP3) of 5dBm while requiring a local oscillator (LO) power of 5.5 dBm with an RF bandwidth of 2 GHz and an IF bandwidth of 400 MHz. The current consumption is about 8 mA with a 3 V voltage supply. The realization of a high output bandwidth and high IF RF mixer is demonstrated to be possible with the floating-body SOS MOSFET.
