CMOS Tunable 1/x Circuit and Its Applications Weihsing LIU Shen-Iuan LIU Publication IEICE TRANSACTIONS on Fundamentals of Electronics, Communications and Computer Sciences Vol.E86-A No.7 pp.1896-1899 Publication Date: 2003/07/01 Online ISSN: DOI: Print ISSN: 0916-8508 Type of Manuscript: LETTER Category: Circuit Theory Keyword: analog signal processing, CMOS, Full Text: PDF(300.9KB)>>
Summary: A new CMOS 1/x circuit is presented in this letter. The output amplitude of the proposed circuit can be adjusted by a bias current. The proposed circuit can be used to realize a current-to-voltage converter and a current-mode divider. The proposed circuits have been fabricated in a 0.5 µm CMOS process. Experimental results show that under the linear error less than  1%, the input range of the proposed 1/x circuit can be up to 1.5 V for the supply voltages of 1.5 V and the power dissipation is 0.24 mW. The experimental results are given to demonstrate the proposed circuits. | ||||||||||
