AMPLIFIER IMPERFECTION EFFECTS IN SWITCHED-CAPACITOR RESONATORS

• Abstract:

  A switched-capacitor bandpass analog-to-digital-converter is one of the circuit blocks used in wireless communication systems to digitize the re- ceived analog signal at certain center frequency (f_c). This particular con- verter is used especially for digital FM or AM radio applications and most of the portable communication devices such as cellular-phones. The main block of this converter is the resonator, which resonates at this f_c center frequency. Two of the main design criteria of the resonators are; to have very high quality resonance peak and to locate the center frequency ac- curately without any shift. However, because of the circuit imperfections, the resonance peak gain and the center frequency have degraded in the previous well-known architectures, seriously.
