The invention discloses a tri-valued, thermal-insulating and low-power adder unit and an adder. The adder unit controls each NMOS tube in an input signal sampling circuit to sample input signals by using a clock-controlled clock signal; four corresponding summing circuit modules and carry output circuits with cross storage-type structures are constructed by sampled values according to required realized addition logic relationship through the bootstrap operation of the NMOS tube; power clocks phi1 and phi complete the evaluation and energy recovery of the output load to realize correct logic function; and compared with a DPL tri-valued adder, the four-digit tri-valued thermal-insulating and low-power adder can save energy consumption by about 90 percent in 0.9 microsecond, and has distinct low-power characteristics.
