In this paper, the operation of super-regenerative (SR) receivers based on super-regenerative oscillators (SRO) is extended to enable the detection of QPSK modulated signals rather than traditional implementation of SR receivers to detect OOK signals. The ability of super-regenerative receivers to properly detect QPSK modulated signals enables using the(More)
In this paper, a complete super-regenerative QPSK receiver is designed to operate at 2.4 GHz while being able to properly receive, process and demodulate incoming signal into raw digital data. The receiver front-end is comprised of an LNA and a super-regenerative oscillator (SRO), both merged for current reuse and lower power consumption. The front-end is(More)
This paper investigates memristor based demodulators and proposes new circuit designs for Binary Frequency Shift Keying (BFSK) and circular 8-Quadrature Amplitude Modulation (QAM) demodulators using two memristors at most. The proposed designs consider utilizing the unique features of the memristor element, crucially, its variable average memristance with(More)
