A high dynamic range Stacked ADCs receiver for long wavelength radio astronomy observations

Abstract : We introduce the design and simulation results of a stacked ADCs architecture that allows the implementation of a wideband and high dynamic range radio astronomy receivers. This work focus on the capabilities of this architecture to make a significant dynamic range enhancement compared to single-ADC based receivers. A detailed analytical analysis of the power consumption shows that this architecture stretches the bandwidth of the receiver up to 100 MHz while being very power efficient. Furthermore, its excellent time-frequency resolution makes this architecture very attractive for spatial exploration missions.
