Abstract:

This letter presents a 3-D Gaussian rendering processor that integrates a spherical beta (SB) illumination module with a mixed-precision rendering engine to enable energy-efficient novel-view synthesis on edge devices. SB replaces spherical harmonics (SH) with a hardware-efficient kernel implemented using a pipelined fixed-point piecewise linear (PWL) power unit. The pipeline …

Inverse Design of Multilayered Pixelated mm-Wave Power Amplifiers

Inverse Design of Multilayered Pixelated mm-Wave Power Amplifiers 150 150
Author(s): Vinay Chenna, Hossein Hashemi

Abstract:

A topology optimization methodology is presented for the design of multistage, multipath, linear and nonlinear millimeter-wave (mm-Wave) power amplifiers (PAs). Optimization algorithms autonomously generate complete multilayered PA core layouts, including actives and passives, with minimal human intervention in just a few days. Experimental results from fabricated linear and nonlinear W-band …
