Home → FAQ and Notes → Analog Design FAQ Analog Design FAQ1. What are the most common basic analog circuit components developed by matricus? Every project development undertaken by matricus is different.The component blocks used in any analog section of an IC are thus varied. Nevertheless, the most common building blocks include:
• operational amplifiers
• differential amplifiers
• audio amplifiers
• high-speed amplifiers
• instrumentation amplifiers
• variable gain amplifiers
• rf amplifiers
• comparators
• power-on_reset
• oscillators
• voltage controlled oscillators
• filters
• sensor interfaces
• analog switches
These building blocks are integrated into a vast range of complete analog functions from A/D converters to PLL synthesizers, clock recovery circuits. power-line communication circuits, etc.
2. Does matricus re-use circuits developed for earlier programs? Certainly re-use would be the ideal approach, both to reduce design costs and to minimize development time-scales. However, this is rarely possible in the market in which matricus usually operates. Each design is very different, function specifications vary considerably and many technologies are addressed. As a result, each block must be developed separately. Certainly there are occasions when designs developed in earlier projects may be used as a start-point, but this save little, since the lion's share of the work is in the fine-tuning and simulation across corners.
