  • Abstract
    A 10 MHz, sixth-order elliptic filter is realized by maximum dynamic range biquads composed of very low-distortion transconductors. Based on precise simulations, the THD of transconductors is lower than -70 dB at 10 MHz for 3 VPP input voltage. For tuning of this filter, an on-chip frequency tuning system is used and also a new Q tuning method based on compensation of transconductors phase shift by variable output resistance of transconductors. All circuits are aimed to be fabricated on a standard 2 μm CMOS process using a single 5 V supply
