5.5.1 Loss of Gain at Low Frequencies Figure 5.8a shows a typical two-stage, RC-coupled amplifier. The coupling capacitors between amplifier stages and any resistance before or after the capacitor form a high-pass filter of the type shown in Fig. 2.1a. The purpose of C is to prevent DC...
flexible op-amp (FLOA)gain bandwidth product (GBW)unity gain frequency (ω_u)In this paper, a sixth-order reconfigurable low pass filter (LPF) is realized using 0.25 μm TSMC CMOS technology. The filter is based on a cascading connection of bi-quadratic active-Gm-RC cells. The active-Gm...
Use FilterCAD to synthesize the filter. Table 1 illustrates the first try, with FilterCAD indicating a classical 7th order lowpass elliptic filter. The filter can be realized by cascading three out of four sections of the LTC1562 (Figure 3), where an external op amp is used to re...

In this paper, a sixth-order reconfigurable low pass filter (LPF) is realized using 0.25 μm TSMC CMOS technology. The filter is based on a cascading connection of bi-quadratic active-Gm-RC cells. The active-Gm-RC cells are realized using compensated op-amps with variable transconductance ga...
The response of Figure 8 makes it obvious that the noise bandwidth of the op amp is much larger than its signal bandwidth. The additional bandwidth does nothing but contribute to the noise, so we can add a low-pass filter on the output to attenuate the noise at frequencies outside the si...
The 1k- 1000pF filter ensures that C1 does not trip due to current spikes or noise during normal operation. A2 supplies whatever drive is required to close the loop, regardless of the output voltage called for. The low, resis- tive saturation losses of the VMOS FETs combined with A2's ...

Because a passive low-pass filter is now between the output pin and the load capacitance, the response at the output pin is typically somewhat peaked, and becomes flat after the roll-off action of the RC network. This response is not a concern in most applications, but can cause clipping ...
