- Abstract
- This paper presents a 2.4-GHz ISM band ultralow-power receiver with a passive sliding-IF (SIF) mixer structure. A self-biased inverter-based low noise amplifier which has high FOM and good linearity in low-power operation is employed. All passive SIF mixer is proposed to avoid power consumption in an active mixer and high-frequency operation of a nonoverlapping 4-phase generator. The passive SIF mixer is analyzed for optimization and interstage matching. A dual mode programmable gain amplifier (PGA) based on Sallen-key low-pass filter is proposed to enhance gain control range. The proposed PGA has 55 dB gain range with power consumption of 120 mu W. The overall receiver has 15-70-dB gain, 6.5-dB noise figure, -10-dBm IIP3 (at 3-MHz tone spacing), and consumes 640 mu W at 2.45-GHz input frequency.
