於此論文中，主要將探討應用於K頻段(1240GHz)系統之相移器、OOK解調接收機與解調機之設計、模擬及量測，其應用如無線通訊系統與低雜訊降頻器(Low noise block)等。
於K頻段應用中，完成一應用於相位陣列傳輸端之反射式相移器，利用改良之型諧振負載以降低損耗變異，並使用變壓器方式呈現已縮小整體晶片面積，模擬完成一具大於200o輸出相位之相移器，在最後並結合上述相移器與可調式驅動放大器，模擬完成一具有360o輸出相位之相位陣列傳輸端電路。
在28 GHz OOK解調接收機中，改良傳統封波檢測器頻寬不足的問題，提出使用Cherry-Hooper回授之檢測器並且加入電感性負載增加頻寬。本論文提出一可解調資料最快到1.2 Gb/s的封波檢測器，中心頻為28 GHz。總功率消耗為49 mW，操作電壓為1.2 V。
在28 GHz OOK解調機中，將傳統的NMOS transistor pair中連結兩個汲極端當作全波整流器，且使用了gain-boosted以及 two cross-coupled capcitors增加轉換增益，並在兩級的基頻放大器中使用Actively-enhanced tunable inductor(AETI)，來調整負載端的LC peaking的頻率點，完成一具有可解調中心頻為28 GHz，資料速率為4Gb/s的OOK解調機。總功率消耗為20.4 mW，操作電壓為1.2 V。

In this thesis, a phase shifter, an OOK demodulation RX and a demodulator in the K-band (1240GHz) are investigated regarding their designs, simulations and measurements. In this frequency band, there are several important applications, such as wireless communications and low-noise blocks(LNB).
For K-band applications, a reflection type phase shifter (RTPS) for phased-array transmitter is implemented. By utilizing the transformer  resonated loads, a compact area is achieved with reduction of loss variations, and. The simulated result achieves at least 200 o phase control range. At last, a full-360o phase shifter is realized, which consists of the proposed RTPS and a tunable driving amplifier. The simulated results of the proposed phase shifter achieves a 360o phase control range, which is suitable for realizing a phased-array transmitter.
For the 28 GHz OOK demodulation receiver, we improve the insufficient bandwidth of the conventional envelope detector, and propose a Cherry-Hooper based envelope detector with inductive peaking to enhance the operation bandwidth. We have realized an envelope detector operating at 1.2 Gb/s, at central frequency of 28 GHz. The total power consumption of the system is 49 mW with a 1.2 V supply voltage.
For the 28 GHz OOK demodulator, we connect two drain terminals in the transistor pair as a full-wave rectifier. By utilizing the gain-boosted technique together with two cross-coupled capcitors, the conversion gain is increased. Also, the actively-enhanced tunable inductor allows adjusting the frequency of the LC peaking at the loading. We realize an OOK demodulator operating at 4 Gb/s, at the central frequency of 28 GHz. The total power consumption of the system is 20.4 mW with a 1.2 V supply voltage.
