Abstract

In this study, in order to inherit the known advantages of the current-mode (CM) operation, a current-mode receiver baseband architecture is proposed for integrated RF receivers. The baseband circuitry is composed of a filter, a variable gain amplifier (VGA), and an analog-to-digital converter (ADC). However, ADC is not in the scope of our study. In the proposed architecture, the voltage-to-current conversion is performed during lowpass filtering in the first stage, where some variable gain is also provided. Thus, lowpass filter and variable gain amplifier is merged in the same stage. The following stage is a lowpass biquad that performs further filtering of the undesired signals. The simulation results show that the proposed architecture is suitable for low-voltage, low-power applications.
