So far, six kinds of medicines are authorised to be applied to the treatment of hypertension by the world health organization ( who ), including diuretics, - receptor blocking agent, - receptor blocking agent, angiotensin receptor antagon, calcium channal blocking agent and angiotensin converting enzyme inhibitors ( aceis )
目前,世界衛生組織( who )批準用於治療高血壓病的一線藥物主要有利尿劑、受體阻斷劑、血管緊張素轉換酶抑制劑( acei ) 、鈣通道阻滯劑( caa ) 、受體阻斷劑、血管緊張素( ang )受體拮抗劑等六大類。Compared with the similar research results, the weighted control ic here has the following characteristics : ( 1 ) the circuit structure is simpler ; ( 2 ) the chip ' s fabrication is compatible with standard cmos process ; ( 3 ) n - mosfets with high w / l ratio and short channels are used for weighting and output to reduce the insertion loss ; ( 4 ) the weighting factor varies in a relatively wide range with the controlling signals ; ( 5 ) input and output impedance approach 50 in low frequency ( e. g. 50mhz ), while in higher frequency they slightly deviate from 50, hence the energy reflection lower than 0. 1 ; ( 6 ) it completes the functions of sampling, weighting, controlling and summing of high frequency analog signals
它的加權控制電路與已報道的相關電路相比具有如下特點:電路結構簡單;製造工藝與普通cmos工藝兼容:短溝道,高寬長比的nmos晶體管具有低的通導電阻,將其作為加權、輸出器件可降低由電路引起的插入損耗;改變加權信號,可實現權值在較大范圍內的連續變化;輸入、輸出阻抗在低頻(如50mhz )下接近50 ,而在高頻下略有偏離50 ,但反射系數均低於0 . 1 ;實現了對高頻信號的取樣、加權、控制、疊加功能的迭加。
