Embodiment Construction
[0027] combine image 3 As shown, the improved sense amplifier circuit of the present invention, in the following embodiments, includes: nine PMOS transistors PM1-PM9, seven NMOS transistors NM1-NM7, two capacitors C1, C2, and two inverters FX1 , FX2, an operational amplifier YF1, a voltage-controlled current source DY3 and a storage unit.
[0028] The sources of the PMOS transistors PM1 and PM4 and the drains of the PMOS transistors PM3 and PM2 are connected to the power supply voltage terminal VDD.
[0029] The source of the PMOS transistor PM3 is connected to the drain of the PMOS transistor PM1, and the connected node is denoted as LD. The source of the PMOS transistor PM2 is connected to the drain of the PMOS transistor PM4, and the connected node is denoted as RD. One end of the capacitor C1 is connected to the node LD, and the other end is connected to the gate of the PMOS transistor PM2, and the connected node is marked as RG; one end of the capacitor C2 is connected ...
