Description

一种汽车电路的稳压电路
技术领域
本发明涉及汽车电路领域,尤其涉及一种汽车电路的稳压电路。
背景技术
在动态随机存取存储器(DRAM)中,电流读出放大器通常被用来读出由位线读出放大器读出的信息。电流读出放大器能够比电压读出放大器读出快,因此电流读出放大器被广泛地使用。电流读出放大器通过传输线来读出电流信号输入,放大电流信号,并将该电流信号输出作为电压信号。电流读出放大器可被要求通过传输线有效地接收电流信号,从而能够正确地读出来自传输线的数据。
通常,使用无源负载电路就能够确定电流读出电路的工作点。然而,由于无源负载电路可能具有相对低的输入电阻,所以可能发生电流信号的损失,并且不能正确地读出数据。
为了减小电流信号的损失,可以增加无源负载电路的输入电阻。然而,如果无源负载电路的输入电阻增加,则可能更缓慢地传输数据。当传输线长度增加、以及电流读出电路和负载电阻之间的距离增加时,这个问题可能更严重。试图解决这个问题,建议使用一种汽车电路的稳压电路理想的电流源来确定电流读出电路的工作点。然而,这个建议可能具有电路体积变得更大、并很难控制的弊端。
图1示出了包括常规无源负载电路的半导体存储器件的电路图。无源负载电路130连接到一对数据线GIO和GIOB。由位线读出放大器110读出并放大的数据通过传输线,即一对数据线GIO和GIOB发送到电流读出放大器140。如果传输门120使用列选择线CSL导通,则由位线读出放大器110读出的数据被载入一对数据线GIO和GIOB,并且在该对数据线GIO和GIOB上发生电流信号的较小的变化。电流读出放大器140读出并放大电流信号I1和I2的变化,并产生响应电流信号I1和I2的输出电压DO和DOB。
常规无源负载电路130包括第一PMOS晶体管P1和第二PMOS晶体管P2。第一PMOS晶体管P1连接在电源电压VCC与数据线GIO之间。第二PMOS晶体管P2连接在电源电压VCC与互补数据线GIOB之间。第一和第二PMOS晶体管P1和P2使用辅助使能信号ONB导通/截止。因此,当使能信号(即,辅助数据使能信号ONB)处于逻辑“低”电平时,第一和第二PMOS晶体管P1和P2导通。当辅助数据使能信号ONB的电平在逻辑低电平不变时,第一和第二PMOS晶体管P1和P2的导通电阻也不变。因此,第一和第二PMOS晶体管P1和P2可作为具有相对不变的电阻的无源元件。
如果由位线读出放大器110读出的数据等于0,并且传输门120导通,则数据线GIO的电平将降低。而且,在数据线GIO地电流信号上发生较小的变化。当数据线GIO的电平降低时,穿过第一PMOS晶体管P1的负载电压增加,并因此,从电源电压VCC通过第一PMOS晶体管P1流到数据线GIO的电流量可能增加。因此,流入电流读出放大器140的电流信号I1中的变化减小。即,可能发生流入电流读出放大器140的电流信号I1和I2的损耗。因此电流读出放大器140可能不能正确地读出数据
