Why do direct conversion receivers amplify only after mixing?
The vast majority of the simple direct conversion receivers I've seen amplify only after mixing. The RF is filtered before mixing, but not amplified at all. For example (from Solid State Design for ...

How Does This Diode Affect This Circuit? [closed]
I am learning about electrical engineering and have a question about this circuit.
I don't have a very niche question, I'm just wondering how the circuit is affected by the addition of the LED.
You ...

Collector current vs. collector-emitter voltage
Why is the collector current in an NPN transistor in CE mode almost independent of the collector-emitter voltage?
Doesn't increasing the reverse bias voltage (Vce) decrease the width of the base (due ...

Why does shorting the drains linearize the transconductance of the differential amplifier?
Why, by shorting the drains in Fig \$14.15\$ in this manner, will it allow the \$G_m\$ plots to add together? What will happen to the \$G_m\$ plot if we swap the shorting transistors, i.e., shorting ...

Transfer function of a heating system
I wanted to design a small temperature-regulated DC heater for the sake of educational purposes in the field of control theory.
The idea is to heat up a resistive element through a buck converter of ...

How can I explain contradictory damping performance between linear and nonlinear systems?
I have a 3rd order nonlinear dynamical system, representing a power system. After linearizing the system, it turns out that by increasing the parameter L_g, damping is reduced and thus the overshoot ...

What did I do wrong with the MCP3426 ADC? - non linear output
I'm running the MCP3426 on 3.3V supply on my PCB. I want to measure a battery voltage from around 12.5V down to 8V. Doesn't have to be precise, 0.1V accuracy is sufficient.
I calculated a voltage ...

Mathematical relation between \$I\$-\$V\$-curve nonlinearity and harmonic distortion spectral components
A nonlinear resistor has a bent/distorted \$I\$-\$V\$-curve. We can approximate its \$I\$-\$V\$-curve with a polynomial model such as:
$$I(V)=I_0 + \frac{1}{R_1}V + \frac{1}{R_2}V^2 + \frac{1}{R_3}V^3 ...

Why do these two sets of seemingly identical capacitors behave differently?
I have two sets of almost identical-looking capacitors which show different behaviour:
The ones on the left (which are definitely these MLCCs) act as I would expect, but the ones on the right (which ...
