counters can replace binary full adders or counters in fast adder structures. The circuits use
recharged CMOS semi-floating gate (RSFG) devices. By using balanced ternary notation, it
is possible to build balanced ternary addition circuits, which can add both negative and
positive operands, by using the same adder blocks. The circuit operates at a clock frequency
of 1 Ghz. The supply voltage 1.0 Volt.
