This work presents a four-channel multiplexer that uses joint T-shaped resonators. The multiplexer contains four second-order bandpass filters that are combined by two joint T-shaped resonators. The ...

In order to investigate the analog-to-digital converter (ADC) suitable for high-quality audio chips, a Sigma Delta modulator implemented using switched-capacitor technology and its digital decimation ...

Though the process of designing a chip using open-source tools may seem daunting at first, it’s an invaluable learning ...
