In this paper we present a sigma-delta modulator for wide-band base transceiver station receivers. The modu-lator, based on a four-path architecture, achieves an equivalent sampling frequency of 320 MHz, although the building blocks operate at only 80 MHz. The circuit in simulation achieves 94 dB signal-to-noise ratio with a signal bandwidth of 5 MHz(More)
