| Abstract: | Based on the characteristics of current-mode circuits, which can easily realize arithmetic operations, the threshold-arithmetic operation, nonnegative operation and threshold arithmetic function are defined in this paper, Besides, HE map is defined and used as the graphic representation of threshold-arithmetic functions. Then the threshold arithmetic algebraic system suitable to design current-mode circuits is established. With current-mode CMOS circuits design examples, the design methods for current-mode CMOS circuits are expounded. The simulation results show that the designed circuits have the correct functions. The threshold-arithmetic algebraic system is a new effective method for designing the current-mode circuits. |
| Keywords: | threshold-arithmetic algebraic system HE map current-mode CMOS circuits |
