Original Titel:
A 1.2-V Triple-Mode Low-Power Receiver Front-End for 900-MHz SRD-Band Applications
This work presents a re-configurable low-power
receiver front-end for SRD-band applications. It provides a
single RX-chain that can be configured into three different
modes of operation, consuming an active power of 0.6mW to
1.44mW. Dependent on the selected mode, wake-up reception,
AM demodulation or IQ demodulation are supported. The design
realizes a digitally selectable narrow-band 500 kHz 4-path filter in
both 868MHz and 915MHz SRD-bands. The test-chip has been
fabricated in a 1P6M 180nm CMOS technology with triple-well
option and achieves a gain of 21 dB with an NF of less than
6.6 dB at a 1.2V supply. With the provided on-chip matching,
the receiver does not require any external RLC components and
enables a maximum of integration.
