- Figure 1. This basic peak log detector shows the principals involved and helps to highlight the problems. (Assume split, non-critical supply rails.)
- Figure 2. This upgraded circuit has a faster response and much better temperature stability
- Figure 4. The simulated and actual response curves are combined here, showing good conformance to a log law with adequate temperature stability
