適用於超高頻系統之可調式無電感CMOS窄頻帶通濾波器的設計

Abstract

在本論文中，我們提出了一個超高頻帶之可調式無電感CMOS窄頻帶通濾波器。 關於主動式電感的設計和濾波器設計流程的議題也在本文中被討論。此濾波器使用0.18微米CMOS製程製造，量測結果顯示當中心頻率調至436MHz時，頻寬為24MHz的濾波器僅有0.1dB的介入損失、-18dB的返回損失和0.51dB的通帶內漣波。此濾波器晶片面積為333 x 653 μm2，消耗功率為62.5mW，量測的1dB壓縮點為-27.1dBm，雜訊指數為17.6dB。

In this thesis, a tunable inductorless CMOS narrow-band bandpass filter at UHF (ultra-high-frequency, 300MHz-3GHz) band is presented. Issues related to active-inductor design and filter design procedure is discussed in detail. The filter is fabricated in 0.18μm CMOS process, measured an insertion loss of 0.1dB, a return loss of 18dB and a 0.51dB in-band ripple with a 436MHz center frequency and 24MHz bandwidth. The filter occupies a chip size of 333 x 653 μm2, with a -27.1dBm input 1dB compression point , a 17.6dB noise figure and a 62.5 mW power consumption.
