Abstract
Official abstract text for this publication.
The CMOS current-mode squaring circuit includes a translinear loop. A rectifier is used to produce the absolute value of the input current. Carrier mobility reduction is taken into consideration to compute the drain current for short channel MOSFETs. Careful selection of CMOS aspect ratios provides error compensation due to carrier mobility reduction.
First claim
Opening claim text (preview).
We claim: 1. A CMOS current-mode squaring circuit, comprising: a translinear loop circuit accepting an input current, |I x |; a rectifier circuit in operable communication with the translinear loop circuit, the rectifier circuit providing the input current |I x | to the translinear loop circuit; a current mirror circuit connected to the translinear loop circuit; and a current subtracting circuit connected to the current mirror circuit, the current subtracting circuit having…
