Abstract: We disclose multiband receivers for millimeter-wave devices, which may have reduced size and/or reduced power consumption. One multiband receiver comprises a first band path comprising a first passive mixer configured to receive a first input RF signal having a first frequency and to be driven by a first local oscillator signal having a frequency about ⅔ the first frequency; a second band path comprising a second passive mixer configured to receive a second input RF signal having a second frequency and to be driven by a second local oscillator signal having a frequency about ⅔ the second frequency; and a base band path comprising a third passive mixer configured to receive intermediate RF signals during a duty cycle and to be driven by a third local oscillator signal having a frequency about ⅓ the first frequency or about ⅓ the second frequency during the duty cycle.

Abstract: We disclose a receiver circuit which may be used in mm-wave devices. The receiver circuit comprises a transimpedance amplifier comprising PMOS and NMOS transistors, wherein the back gate voltages provided to the transistors may be adjusted. By adjusting the back gate voltages during device operation, structural variations and temperature variations in the threshold voltages of the transistors may be minimized and the gain compression tolerance of the receiver circuit may be increased.
