A very linear BiCMOS transconductor for high-frequency filtering
A differential transconductance stage implemented in BiCMOS technology is described. The key features of the new stage are: (1) a total harmonic distortion (THD) less than 0.15% up to a 3 V/sub pp/ differential input signal, assuming 2% mismatch of the input devices, with a 5-V supply; (2) a second pole frequency typically higher than 2 GHz; and (3) a gain of …

Cutoff Frequency. As with low-pass filters, high-pass filters have a rated cutoff frequency, above which the output voltage increases above 70.7% of the input voltage. Just as in the case of the capacitive low-pass filter circuit, the capacitive high-pass filter's cutoff frequency can be found with the same formula:

High Pass Filter : Circuit, Characteristics and Its Applications
The output and the cut-off frequency of the passive high pass filter is controlled by the op-amp. Where the bandwidth and gain characteristics of op-amp determine the cut-off frequency. This type of filter acts as a bandpass filter. The op-amp increases the amplitude of the output signal and the output voltage gain of the passband …

High frequency analysis and modeling of EMI filter
In many cases, EMI filter plays a key role in EMC design. However, the performance of EMI filters, especially in high frequency, is often different from previous estimates. Based on this situation, this paper first theoretically calculates the performance of EMI filter, and then analyzes the effect of the parasitic parameters of each component of the filter and its …

Multiresonant-Frequency Filter for an Electrosurgery Inverter
This letter presents a multiresonant-frequency (MRF) filter for a high-frequency inverter (HFI) used in electrosurgery. The fundamental (sinusoidal) output frequency of the HFI is 390 kHz and is the same as the switching frequency of the HFI. The MRF is designed to extract the fundamental frequency of the tri-state bipolar waveform, generated by the …

How do smaller capacitors filter out higher frequencies than …
If practical capacitors were purely capacitive, then indeed, a larger capacitor would do an even better (or at least "as good") job of filtering high frequencies as a smaller value one.. But capacitors are not purely capacitive; ones we can practically build are also unfortunately inductive, and at some frequency the inductive behavior …

Frequency filtering
Frequency filtering can be in the form of band-pass, band-reject, high-pass (low-cut), or low-pass (high-cut) filters. All of these filters are based on the same principle — construction of a zero-phase wavelet with an amplitude spectrum that meets one of the four specifications.

What Is An Audio High Pass Filter? How Are They Used?
While a highpass filter allows higher frequencies to pass, a low pass filter (LPF) crossover works to block high frequency sounds above the cutoff frequency.. These are often used for woofers and subwoofers but can also be used as part of a 2-way speaker design. A HPF filter would be used for the tweeter portion of the design.
