Abstract :
This paper presents a design of an analog programmable, low-noise, low-voltage, low-power, continuous-time baseband filter. This baseband filter will be used as a part of the baseband section in the direct conversion receiver and is designed to meet the baseband signal specifications required for both the digital enhanced cordless telecommunications (DECT) and the cellular (GSM, PCS 1900, DCS1800) standards. This baseband filter is designed in a standard 0.8 μm CMOS technology with threshold voltages VTN = 0.7V for NMOS and VTP = -0.9 V for PMOS transistors. It consumes only 4.3mW from a 3.0V supply voltage. The designed baseband filter presents a high dynamic range of about 84dB.
