Low-Power ${G}_{{m}}{-}C$ Filter Employing Current-Reuse Differential Difference Amplifiers Academic Article uri icon

abstract

  • 2004-2012 IEEE. This paper deals with the design of low-power high-performance continuous-Time filters. The proposed operational transconductance amplifier architecture employs current-reuse differential difference amplifiers in order to produce more power-efficient s filter solutions. To demonstrate this, a sixth-order low-pass Butterworth filter was designed in a 0.18- CMOS, achieving a 65-MHz-3-dB frequency, an in-band input-referred third-order intercept point of 12 dBm, and an input-referred noise density of 40 nV/Hz1/2, while only consuming 8.07 mW from a 1.8-V supply and occupying a total chip area of 0.21 mm2 with a power consumption of only 1.19 mW per pole.
