Abstract
This paper presents a new top-level design of an analog on-chip spectrum analyzer which exploits the Miller regenerative frequency divider (RFD) in its architecture. So
input spectrum is down-converted to lower frequencies in twosteps that leads to relaxing the need for external high-frequency local oscillator (LO) as well as solving the multi-tones input signal processing drawback in the Miller frequency dividers. The presented analog spectrum analyzer has been designed for the IEEE 802.11b wireless local area network (WLAN) frequency band. Also the range of external LO frequency varies from 1.4 GHz to 1.483 GHz to shift the input signal around 1 GHz. The power of each sub-carrier of input signal is -12 dBm, and the signal to noise and distortion ratio (SNDR), in the worst case, is 40 dB.
