Abstract

This paper presents single amplifier biquads and Active-gm-RC cells with programmable unity gain frequency operational amplifiers. A complete baseband chain for Software-Defined Radio is designed using these building blocks. The baseband chain consists of a reconfigurable low pass filter (LPF) and a variable gain amplifier (VGA). The LPF is a sixth order filter with cutoff frequency range from 380 kHz to 33.4 MHz. The VGA is made of two cascaded gain stages. The baseband chain is realized in 0.25µm CMOS technology with 1.2V supply voltage. PSPICE simulations are presented.

用于软件定义无线电接收机的可重构基带链

本文介绍了带有可编程统一增益频率运算放大器的单放大器双四边形和有源-gm-RC 单元。利用这些构件设计了用于软件定义无线电的完整基带链。基带链包括一个可重新配置的低通滤波器（LPF）和一个可变增益放大器（VGA）。LPF 是一个六阶滤波器，截止频率范围为 380 kHz 至 33.4 MHz。VGA 由两个级联增益级组成。基带链采用 0.25µm CMOS 技术实现，电源电压为 1.2V。本文介绍了 PSPICE 仿真。
