Non-Orthogonal Multiple Access (NOMA) is considered as a promising downlink Multiple Access (MA) scheme for future radio access. In this paper two power allocation strategies for NOMA are proposed. The first strategy is based on channel state informa

A time-to-digital converter (TDC) is proposed to replace the multi-bit quantizer and the multi-bit feedback DAC of traditional voltage-mode ΣΔ modulator. Since time-mode systems process analog signals encoded in the time dimension rather than the v

This paper proposes an architecture and design approach for the realization of wideband millimeter-wave frequency synthesizers. This architecture uses two-step multi-order harmonic generation of a low frequency phase-locked signal to generate wideban

A third-order CT ΔΣ ADC that replaces the multi-bit quantizer and feedback DAC by a pulsewidth modulation (PWM) generator and time-to-digital converter (TDC) is implemented in 65 nm CMOS technology. The TDC provides a 50-level binary output code an

An architectural solution for designing and implementing low THD oscillators is presented. A digital harmonic-cancellation-block is used to suppress the low-frequency harmonics while a passive, inherently linear, filter is used to suppress the high-f
