Strange low frequency sawtooth in a 110 kHz Hartley oscillator
I am trying to build a Hartley oscillator for 110 kHz using a BJT according to the following schematic:
I am assuming \$ \beta=100\$ and \$ V_t=25mV \$
The collector current is about 1.63 mA, Vc is ...

Class-D audio amplifier produces a sawtooth wave on the output, not sine
I am using a MAX9744 Class-D amplifier and want to get a sine wave in the output. Someone suggests using an LC low-pass filter for this, and in the datasheet of the amplifier, the values for inductors ...

Effects of ferrite isolator on waveform
I have recently measured the standing wave signal from a waveguide. I notice that as the frequency is lowered the signal tends towards a sawtooth wave.
**
My guess for why this happens is that the EM ...

Producing a sawtooth wave from a square wave
I am trying to produce a sawtooth wave from a 2 MHz square wave. For this, I am using an LT1800 op-amp.
I want to get a -5V to 5V sawtooth wave shape.
I did not do this in LTspice. I made the ...

How to spec a power supply for capacitor charging given the simulation and large requirements?
I am using the LT3751 as a capacitor charger for a large capacitor (30mF) and am trying to get an idea of the kind of power supply I would require in order to come close to the simulation charge time. ...

How do you sketch a signal given by x(t) = A(t/T) for time period 0 to T? Does t/T simply denote that the signal covers entire duration of T?
Does t/T simply mean that the signal has magnitude A over the entire "T" duration? Or does it mean that it covers only a fraction? How will it look?
I tried assuming A to be some magnitude ...

AC DC adapter sawtooth current draw above rated value
I will be using AC DC wall adapter to power the flyback converter. Power adapter is rated 15V@3A = 45W.
The question is, can I draw peaks over 3A if I stay below 45W on average?
For example, with the ...

How to design a sawtooth wave generator? (Required specification of sawtooth wave 0-14V and 50kHz)
I tried using ICs like the ICL-8038 and the 555 time. It didn't work out because of the supply voltage constraint. I also tried using an op-amp (LTC6244) based circuit. It gave a distorted wave at ...

Sawtooth waveform used for wireless battery charging
Why don't we use sawtooth AC waveforms instead of the sinusoidal ones? Since the rate of change of voltage is steady for a purely resistive circuit the rate of change of current is costant-> linear ...

How to use an op-amp (that only uses ground and positive voltage to operate) to create a sawtooth/triangle wave generator?
The design I have in mind will be battery operated, so I have found the TL972 (Datasheet Here) which only operates from 0 - 12 V.
What I want this op-amp to do is to create a sawtooth/triangle wave ...
