Description: An original
proposal of using SRO-based receiver to demodulate QPSK signals is presented. The receiver is
composed of an LNA and a super-regenerative oscillator (SRO), both combined in a single stacked config-
uration
for current reuse. The demodulation of received RF signal is performed via a novel digital circuit
capable
of detecting phase information embedded in the SRO output. The receiver is able to demod-
ulate
incoming signal without the need of an LO, PLL or an ADC. The complete receiver was designed
using
a 0.13 m technology and pre-layout simulation confirms proper and efficient operation, where
the
designed receiver operating in the 402–405 MHz MICS band shows 135 W power consumption,
while
being able to properly detect and extract sent informatio
