Abstract
This paper presents a reconfigurable tri-level/multi-bit multi-mode ΔΣ modulator implemented in 0.13 μm CMOS. The modulator covers between 0.1 MHz and 20 MHz signal bandwidth which makes it suitable for cellular applications including 4G radio systems, also known as IMT-Advanced. With a maximum sampling rate of 400 MHz, the modulator achieves between 86 dB and 70 dB DR for 100 kHz and 20 MHz signal bandwidth, respectively, at a scalable power consumption between 2 mW and 34 mW from a 1.2 V supply, including the reference buffer.
