上节提到的CS没有考虑到 channel-legth modulation 和 Body-effect , 这节仅将前者考虑进去,因为可能会影响较大,仍然不考虑 Body effect(即 \lambda e0,\gamma=0 ) 讨论范围仅限在MOS在饱和区,所以 V_{OUT}=…
The common source (CS) amplifier and resistive load inverter are investigated and gain is determined. The CS amplifier exhibits higher gain (VOUT/VIN) with the asymmetric spacer. Further, a resistive load inverter is designed and demonstrated to realize optimal performance by varying the resistive ...
“Class A NPN Emitter-Follower Amplifier” lab, the emitter-follower output resistance is low, which is desirable for a voltage amplifier output, but is not desirable for a voltage amplifier input. With a low-impedance voltage source providing the base bias, the common-base input resistance is...
with respect to the cathode, providing the bias operating point for the tube. This resistor controls the headroom of the stage (output before clipping) and linearity, or distortion level, of the stage. As the bias point is shifted, the amplifier will clip more on the top or bottom portion...
If All Else Fails, Read This Article Avoid Common Problems When Designing Amplifier Circuits By Charles Kitchin [charles.kitchin@analog.com] Introduction Modern operational amplifiers (op amps) and instrumentation amplifiers (in-amps) provide great benefits to the designer, compared with assemblies of ...

19-2842; Rev 3; 6/09 80mW, DirectDrive, Stereo Headphone Amplifier with Common-Mode Sense General Description The MAX4409 stereo headphone amplifier combines Maxim's DirectDrive® architecture and a common- mode sense input, which allows the amplifier to reject common-mode noise. Conventional...
In one of the earlier examples, the power output of an amplifier was expressed as peak power. The voltage used to calculate the power output into the resistive load was peak voltage. The next section will explain the different ways to measure voltage. ...
We'll illustrate these limitations for MOSFET amplifier input stages. Figure 1-1 shows a simplified representation of an N-channel MOSFET input stage. The stage consists of a current source (single NMOS, Q3, shown for simplicity), a differential pair with input voltage applied to the gate of...
9.2 Typical Application The device is a unidirectional, current-sense amplifier capable of measuring currents through a resistive shunt with shunt common-mode voltages from −16 V to 80 V. Two devices can be configured for bidirectional monitoring and is common in applications that include charging...
