摘　　要：传统绝热电路ECRL(Efficient Charge Recovery Logic)有两个缺点,其一是电路节点能量不能被完全回收;其二是电路的功耗随着负载电容的增大而增加。对此提出了两种改进型电路,一种是构造一条能量回收通路,使得未回收的能量通过构造的通路得到回收,用有限的绝热损失实现非绝热能量的完全回收;另一种是通过自举操作使得电路的非绝热过程仅涉及电容较小的驱动MOSFET管,与负载电容不直接相关。采用0.5μm BSIM3v3模型工艺的HSPICE对上述电路进行仿真,结果表明,与ECRL电路相比,两种改进型电路的功耗均有一定程度的降低。Traditional ECRL（Efficient Charge Recovery Logic） adiabatic circuit has two disadvantages. One is that the energy of the circuit nodes can not be completely recycled; The other is that the power consumption is rapidly raised with the increase of load capacitance. Two improved circuits overcoming two disadvantages are proposed. One is to construct an energy recovery path, through which the energy un-recycled is recovered to achieve full recovery with limited non-adiabatic adiabatic energy loss. The other is to make the non-adiabatic process of the circuit associate with only the smaller MOSFET gate capacitance instead of the load capacitance by a bootstrap operation. The HSPCIE simulation with 0.5 I, Lm BSIM3v3 model technology proves that the power consumption of the two improved circuit has a certain degree of reduction compared to ECRL circuit.
