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 ...
V_{in,CM} 还会在不完全对称的 Differential Pairs 中会影响Differential gain,如下图为一个Resistive load不对称结构, R_{D1}=R_{D},R_{D2}=R_{D}+\Delta R_{D} 不对称结构 假设\gamma=\lambda=0 ,根据source follower \frac{\Delta V_{P}}{\Delta V_{in,CM}}=\frac{R_{SS}}{R_{SS...

When the current source ICTRL injects zero current into RA, the output voltage of the buck converter is the maximum positive value (VBUCK(MAX)) relative to the negative rail and maximum output voltage (+ VOUT) relative to GND. To produce a negative output vo...
Before moving on to the common errors in discrete components, it is necessary to understand the source of these breakages. The following are the potential causes: Voltage fluctuation Component aging Excessive heat Corrosion To mitigate these causes consider these guidelines: ...
Low-noise preamplifier for magneto-resistive heads A d.c. current source (17) provides current through a field effect transistor (12) and the effective resistance (18) of a magneto-resistive element to ground. A feedback loop including an operational transconductance amplifier (26) provi... ...

为了简化计算,忽略两种效应,第一级是CS stage with source degeneration之前有说在这种情况下的增益为-(Resistance tied between Drian and ac GND)/ (\frac{1}{g_{m}}+Resistance tied between source and ac GND),第二级是common gate 那么A_{v}=\frac{v_{out}}{v_{in}}=\frac{v_{x}}{v_{in...
If the total resistance formed by the intrinsic, external and driver resistances is much lower than the equivalent MOSFET impedance between gate and source, the coupled capacitive current flows through the resistive path mentioned above. The capacitive current causes spurious bouncing across the gate ...
