A 28 GHz Static CML Frequency Divider with Back-Gate Tuning on 22-nm CMOS FD-SOI Technology
…11mW from 0.86V supply and occupies 800μm² of area. Small area allows to place divider-by-2 block next to IQ mixers in a direct conversion or sliding IF transmitter or receiver….
Massive MIMO Detection Techniques
…community due to their deterministic dataflow and low complexity. We also briefly explore several nonlinear small-scale MIMO (2—4 antenna receivers) detectors and their applicability in the massive MIMO context. In…
Two-Stage Internal DAC Mismatch Mitigation for a Continuous-Time Delta-Sigma ADC
…viable for Delta-Sigma analog-to-digital data conversion. Here, the static portion of the DAC mismatch is linearized in the DAC feedback and the dynamic portion will be linearized digitally. Measuring and…
Chip-to-chip interfaces for large-scale highly configurable mmWave phased arrays
…The RFIC incorporates four C2C interfaces operating at 27 GHz, two C2C interfaces operating at 9 GHz, and a complex baseband (BB) with single-sided bandwidth in excess of 400 MHz….
Equalization of Frequency Selective Channels Using Multirate Signal Processing
Multirate signal processing techniques for the equalization of frequency selective communications channels are proposed. It is shown that a multirate equalizer (MRE) is substantially less complex compared to the conventional…
The fox and the hound
Cu(In,Ga)(S,Se)₂ (CIGS) thin film solar cells require appropriate depth and lateral distributions of alkali metal dopants and gallium to attain world record photovoltaic energy conversion. The two requirements are interdependent…
A User-Centric Mechanism for Sequentially Releasing Graph Datasets under Blowfish Privacy
In this article, we present a privacy-preserving technique for user-centric multi-release graphs. Our technique consists of sequentially releasing anonymized versions of these graphs under Blowfish Privacy. To do so, we…
Proxy Experience Replay
…interpolated using the mixup data augmentation algorithm. Simulations in a Cartpole environment validate the effectiveness of MixFRD in reducing the variance of mission completion time and communication cost, compared to…
A hybrid approach for paraphrase identification based on knowledge-enriched semantic heuristics
…The essence of the proposal is to distinguish the computation of the semantic similarity of named-entity tokens from the rest of the sentence text. More specifically, this is based on…
