With ever increasing demand of IoT based sensor systems, there is a need to assess the
performance of wireless sensor networks especially in indoor environment. In these …

A dual-mode radio frequency CMOS power amplifier (PA) for Internet of Things application is
presented, which is integrated with the other circuits in a 55-nm bulk CMOS process. The …

This paper presents a single-bit RF transmitter based on single-bit switched-capacitor RF
digital-to-analog converters (DACs) embedded in an finite-impulse response (FIR) filter (FIR …

A delay-locked loop (DLL) based RF-PWM generator is proposed for broadband signal
modulation. The approach can be applied to a Cartesian transmitter in combination with a …

Broadband receiver architectures for full-band or concurrent multi-band reception of signals
are required in several applications. One approach to implementing such receivers is a …

(57) ABSTRACT A system for generating an RFPWM signal comprises a delta sigma
modulator having a plurality of outputs, a phase-locked loop comprising a plurality of phase …

Pulse width modulation (PWM) is an attractive signaling method since it can represent an
analog signal while using a discrete-level signal, and is hence more robust to amplitude …

Modern Communication systems are progressively moving towards all-digital transmitters
(ADTs) due to their high efficiency and potentially large frequency range. While significant …

All-digital transmitters enable the constantly desired integration of both radio-frequency front
ends and digital baseband in a single low-cost monolithic chip. Thus, the widespread of this …
