(d) Expected VBBPSRR frequency response of Fig. l(a). A2 = gm2Rz = clc gain of the second stage. (1) Fig. 2(b) shows its pole-zero location. Notice that there is no finite zero in this circuit and that both the poles are real and are widely spaced. (2) (3) Assuming the ...
If there are two or more dominating poles, the phase margin of the frequency response is negative, and overall feedback of the OpAmp is not possible. To change this, frequency compensation techniques must be applied that give the OpAmp one dominating pole frequency with a straight 6-dB/octave...
Hello, I have a doubt about the high frequency response of the MOSFET (or BJT as well) differential couple in the case it's polarized by a current mirror. Here's a picture of my issue (it shows the semi-differential circuit of a MOSFET differential couple with a "small" common mode ...
Sampling and re-sampling the data based of multiple rounded cycles of your 12khz source, IE a software simulated PLL is really powerful as you can set deliberate high and low cutoff response frequency ranges from your 12khz source.If you are looking at sampling signals from a helical or lida...
The analysis of biomedical signals for clinical studies and therapeutic applications can benefit from embedded devices that can process these signals locally and in real-time. An example is the analysis of intracranial EEG (iEEG) from epilepsy patients f
5-62 Since the gain of a bandpass filter peaks at FBP instead of F0, an adjustment in the amplitude function is required to normalize the response of the aggregate filter. The gain of the individual filter section is given by: where: √ ( )AR = A0 1 + Q2 F0 FBP - FBP F0 2 A0 ...

output impedance, Ro. At unity gain frequency Ro and R of snubber must form a resistive voltage divider, to do two things: Decreasing the gain of OPAmp so that a lower portion of output signal is fed back to the inverting input, and doing this without introducing an additi...
Thanks for your response and patience :-) I am a Professor of Chemistry (University Researcher in Brazil) and I am interested in the area of:EIS - Electrochemical Impedance Spectroscopy ( below SITE reference in [1] ). In an EIS study, the frequency region of 100kHz to 1uHz is very ...
A transistor is switched with a control circuit in response to the control current sensor circuit and an oscillator that is coupled to a trim circuit, which is trimmed during manufacture of a circuit, to regulate the output of a power supply. A current through the transistor is limited with ...
