  • Abstract
    A new topology and design method for continuous-time (CT) band-pass delta-sigma modulators is presented in this paper. The proposed modulator employs a lamb wave resonator (LWR) possessing high Q-factor. This kind of resonator presents many advantages comparing with the LC or Gm-C resonators. Furthermore, the proposed topology is entirely compatible with the LWR transfer functions. This method facilitates the design of band-pass delta-sigma modulators in a wide range of central frequencies (fc).
