Analog CMOS Low-Voltage Current-Mode Implementation of Digital Logic Gates
نویسنده
چکیده
In this paper a new approach is introduced for implementing the basic logic functions using analog current-mode techniques. By expanding the logic functions in power series expressions, and using summers and multipliers, realization of the basic logic functions is simplified. To illustrate the proposed technique, a CMOS circuit for simultaneous realization of the logic functions NOT, OR, NAND and XOR is considered. HSPICE simulation results, obtained with ± 3.5V supply, are included.
