Reconfigurable baseband chain for Software-Defined Radio receivers
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.
