Description
Summary:In this paper a novel sampler that performs beam-forming is introduced. Several parts of the receiver chain are combined into one compact sub-sampling beam-forming summation track and hold (SSBS-TH). It directly integrates a true time delay with a phase correct summation unit. Furthermore the proposed circuit includes the sampling capacitance of a time interleaved (TI) analog-to-digital converter (ADC). The SSBS-TH operates at 12 GS/s to enable wide-band operation and cover frequencies up to 6 GHz. Therefore it is suitable for software defined radio (SDR). An overall linearity of 56 dBc and a signal-to-noise ratio (SNR) above 52.8 dB is achieved.
