“…7), and we came up with a high-frequency signal estimation circuit using multiple low-frequency sampling circuits following an analog Hilbert filter (RC polyphase filter) and ADCs (Fig. 8) [24,25]; here the sampling frequencies are relatively prime. A sinusoidal signal with high frequency is provided as an input signal.…”

This article reviews the author's group research achievements in analog/mixed-signal circuit and system area with introduction of how they came up with the ideas. Analog/mixed-signal circuits and systems have to be designed as well-balanced in many aspects, and coming up ideas needs some experiences and discussions with researchers. It is also heavily dependent on researchers. Here, the author's group own experiences are presented as well as their research motivations.
