Choice of op-amp structure
There are three important operational amplifier structures: (a) simple two-stage op-amp, (b) folded cascade, (c) cascade.
The design index of the operational amplifier designed this time requires a differential output amplitude of ±4V, that is, the sum of VDSAT and N of all NMOS transistors at the output end is less than 0.5V, and the sum of VDSAT and P of all PMOS transistors at the output end must also be less than 0.5V.
Main op amp structure
The operational amplifier has two stages:
(1) Cascode stage increases DC gain (M1-M8);
(2) Common source amplifier (M9-M12).
Common mode negative feedback
For a fully differential op-amp, in order to stabilize the output common-mode voltage, a common-mode negative feedback circuit should be added.
When designing a fully differential operational amplifier with balanced output, the following points must be considered:
The open-loop DC gain of common-mode negative feedback is required to be large enough, and it is best to be equivalent to the differential open-loop DC gain;
The unity-gain bandwidth of common-mode negative feedback is also required to be large enough, preferably close to the differential unity-gain bandwidth;
In order to ensure the stability of common-mode negative feedback, common-mode loop compensation is generally required;
Common-mode signal monitors are required to have good linearity characteristics; common-mode negative feedback has nothing to do with differential-mode signals, even if the differential-mode signal path is turned off.
The operational amplifier adopts a continuous-time model to realize the common-mode negative feedback function.
This structure shares the current mirror and output load in the input stage of the common-mode amplifier and the differential-mode amplifier. In this way, power consumption is reduced on the one hand;
On the other hand, it is ensured that the common-mode amplifier and the differential-mode amplifier maintain the same AC characteristics.
Because the output stage of the common-mode amplifier and the output stage of the differential-mode amplifier can be completely shared, the capacitance compensation circuit is the same.
As long as the frequency characteristic of the differential mode amplifier is stable, the common mode of negative feedback is also stable.
This common-mode negative feedback circuit allows the fully differential operational amplifier to be designed like a single-ended output operational amplifier, regardless of the effect of the common-mode negative feedback circuit on the fully differential amplifier.
Voltage bias circuit: wide swing current
Three voltage biases are required in the cascade input stage. In order to make the dynamic range of the input stage larger, a wide swing current source is used to generate the required three bias voltages.
