Abstract

Discrete-time (DT) circuits provide a means to overcome the analog-circuit design challenges in deeply scaled digital CMOS technologies while benefitting from the reduced switch on-resistance and parasitic capacitance, resulting in lower dynamic power dissipation. In addition, such DT analog circuits can reduce the requirements on analog-to-digital converters that precede digital processing [1]. Recent DT domain filters achieve high-order narrowband programmable filtering with low power and high linearity even under low supply voltage [2,3]. However, DT switched capacitor circuits have not been considered for wideband analog signal processing (ASP) applications such as on-chip implementation of FIR-based beamforming [4,5]. While the AFIR filter proposed in [6] is a suitable approach for programmable wideband ASP applications, in that design only symmetric and positive coefficient sets were possible and measured performance was not shown.

一种低功耗3.25GS/s的四阶可编程模拟FIR滤波器,采用分路cdac系数乘法器,用于宽带模拟信号处理
离散时间(DT)电路为克服深度缩放数字CMOS技术中的模拟电路设计挑战提供了一种方法,同时受益于降低开关导通电阻和寄生电容,从而降低动态功耗。此外,这种DT模拟电路可以减少对数字处理之前的模数转换器的要求[1]。最近的DT域滤波器即使在低电源电压下也能实现低功耗和高线性度的高阶窄带可编程滤波[2,3]。然而,DT开关电容电路尚未被考虑用于宽带模拟信号处理(ASP)应用,如基于fir的片上波束形成[4,5]。虽然在[6]中提出的AFIR滤波器是一种适用于可编程宽带ASP应用的方法,但在该设计中,只有对称和正系数集是可能的,并且没有显示可测量的性能。
