چکیده
This paper presents a spatial-temporal single harmonic switching (STHS) transmitter array architecture with enhanced efficiency in the power back-off (PBO) region. STHS is an electromagnetic and circuit co-designed jointly optimized that realizes beamforming generation at same time. The temporal dimension originally added to achieve enhancement, which can be combined conventional enhancement methods such as Doherty amplifiers envelope tracking. design validated through simulation of two-stage amplifier 65-nm CMOS 77 GHz, achieves peak drain (DE) 24.2%, 22% DE 3-dB PBO, 16% 6-dB 10.2% 9-dB PBO. exhibits 57% improvement 100% 190% PBO compared class A/B amplifier.

Design of a High Range, High Efficiency Spread Spectrum Transmitter for Audio Communication Applications
This work proposes a direct sequence spread spectrum transmitter with high transmission range and efficiency for audio signals. It is shown that by choosing high process gain for spread spectrum signal the data could reach a range of 55km in the 2.4GHz ISM band. By employing a light modulation scheme, we have a relaxed SNR requirement for having a low bit error rate (BER) which translates to re...
متن کاملTwo-Level Spatial Multiplexing using Hybrid Beamforming Antenna Arrays for mmWave Communications
In this work, we consider a two-level hierarchical MIMO antenna array system, where each antenna of the upper level is made up of a subarray on the lower one. The concept of spatial multiplexing is applied twice in this situation: Firstly, the spatial multiplexing of a Line-of-Sight (LoS) MIMO system is exploited. It is based on appropriate (sub-)array distances and achieves multiplexing gain d...
متن کاملFully Integrated CMOS Switching Power Mixer Array for Linearization and Back-Off Efficiency Improvement
Non-constant envelope modulation schemes have become commonplace in cellular applications due to their higher spectral efficiency. Linear PAs driven by an RF transmitter are usually used to generate these signals faithfully at the expense of power efficiency. Separate processing of amplitude and phase information (e.g., EER or polar modulation) has been proposed [1] as a way of improving the sy...

The ever increase of nonlinear loads in electric distribution networks causes many problems due to the high level of harmonic currents. This paper proposes a new technique for controlling a single phase shunt active power filter based on a selective compensation using the newly developed technique of harmonic control arrays. Simulation results confirm the appropriate selective harmonic compensa...
