New Mapping Strategies for Pre-Optimized Inductor Sets in Bottom-Up RF IC Sizin...
Lourenço, N.; Martins, R.; Póvoa, R.; Canelas, A.; Horta, N.; Passos, F.; Castro López, R.; Roca, E.; Fernández, F.This paper presents new indexing and mutation operators, in the context of bottom-up hierarchical multi-objective optimization of radio frequency integrated circuits, for pre-optimized sets of solutions from the hierarchical sub-levels when moving up in hierarchy. Two ideas, one based on a Voronoi decomposition and another based on the nearest neighborhood, are explored, where, and unlike previous approaches th...
Systematic Design of a Voltage Controlled Oscillator using a Layout-Aware Approach
Passos, F.; Castro Lópes, R.; Roca, E.; Fernándes, F.; Martins, R.; Lourenço, N.; Póvoa, R.; Canelas, A.; Horta, N.This paper focuses on the systematic design of voltage controlled oscillators (VCO), a commonly used radiofrequency (RF) electronic circuit. RF circuits are among the most difficult analog circuits to design due to its trade-offs and high operation frequencies. At such operation frequencies, layout parasitics and accurate passive component characterization become of upmost importance, causing re-design iteratio...
Layout-Aware Challenges and a Solution for the Automatic Synthesis of RadioFreq...
Martins, R.; Lourenço, N.; Póvoa, R.; Canelas, A.; Horta, N.; Passos, F.; Castro López, R.; Roca, E.; Fernández, F.In this paper, the major methodologies proposed in the last years to speed-up the synthesis of radio-frequency integrated circuits blocks are overviewed. The challenges to automate this task are discussed, and, to avoid non-systematic iterations between circuit and layout design steps, the architecture of an innovative solution is proposed. The proposed tool exploits the full capabilities of most established co...
