An Open-Source Standard-Cell Library for IHP 130nm Developed by Students
Oscar Castañeda, Lavinia Recchioni, Tobias Senti +26
Standard-cell libraries form the critical interface between transistor-level circuit design and automated digital design flows, yet their design and characterization are rarely cov…
A 14ns-Latency 9Gb/s 0.44mm 62pJ/b Short-Blocklength LDPC Decoder ASIC in 22FDX
Darja Nonaca, Jérémy Guichemerre, Reinhard Wiesmayr +2
Ultra-reliable low latency communication (URLLC) is a key part of 5G wireless systems. Achieving low latency necessitates codes with short blocklengths for which polar codes with s…
Fixed-Throughput GRAND with FIFO Scheduling
Filippo Christen, Darja Nonaca, Christoph Studer
Guessing random additive noise decoding (GRAND) is a code-agnostic decoding method that iteratively guesses the noise pattern affecting the received codeword. The number of noise s…
Optimizing Puncturing Patterns of 5G NR LDPC Codes for Few-Iteration Decoding
Reinhard Wiesmayr, Darja Nonaca, Chris Dick +1
Rate-matching of low-density parity-check (LDPC) codes enables a single code description to support a wide range of code lengths and rates. In 5G NR, rate matching is accomplished…
A 1.2 mm 416 mW 1.44 Mmat/s 6416 Matrix Preprocessing ASIC for Massive MIMO in 22FDX
Darja Nonaca, Christoph Studer
Massive multiuser (MU) multiple-input multiple-output (MIMO) enables concurrent transmission of multiple users to a multi-antenna basestation (BS). To detect the users' data using…
