A 90nm CMOS active inductor band pass filter with automatic peak detection is demonstrated in this thesis. The active inductor band pass filter has a better performance than the passive band pass filter in on-chip circuit design, due to small area, larger gain and tunable frequency. However, process variation makes the active inductor band pass filter hard to be used widely in many applications. To settle this issue, an automatic voltage peak detector is introduced to detect the process variation direction and hope to be used to control the active inductor band pass filter center frequency and gain. The designed active filter shows center frequency of 6GHz and quality factor (Q) of 31.9. To drive the peak detector, two analog buffers are designed with f-dB over 6GHz, and one has 0dB gain at low frequency region, another one would emphasize 0dB gain on 6GHz. The voltage peak detector can detect the AC input amplitude range from 0.06V to 0.6 and produce a linear output DC voltage of 77.97mV to 726.65mV.
