A general high-Q biquad lter architecture capable of operating in the GHz range is proposed and analyzed. This lter, which is usable in bandpass and lowpass applications, utilizes two e ective Q-enhancement techniques to circumvent the low-Q characteristics inherent in the circuit. Simulation results employing standard 0.5 m CMOS technology have successfully veri ed that the center frequency tu...

A band-pass filter with 70% bandwidth, effectively functioning as a pseudo-high pass filter has been designed and implemented using suspended strip-line technology. In principle such a filter can easily be fabricated by cascading low pass and high pass filters, but it is difficult to fabricate high pass filters in suspended stripline, and this filter is expected to overcome this difficulty. The...

This paper provides a voltage mode (VM) multi input single output (MISO) universal filter with the help of voltage differencing inverting buffer amplifier (VDIBA). All the filter functions i.e., Low pass, band pass, band reject, high pass, and all pass filter functions can be realized without modifying the circuit configuration. The pole frequency can be independently tunable by its transconduc...

A second order voltage mode tunable universal filter is presented. The voltage mode filter is based on dual output second generation current controlled current conveyor (DOCCCII). The filter is capable of realizing high pass (HP), low pass (LP), band pass (BP), notch pass (NP) and all pass (AP) responses in voltage mode (VM). The filter employs only two capacitors and hence enjoys minimum compo...

A two-input two-output (TITO) current-mode universal biquad using only four dual-output operational transconductance amplifier (DO-OTAs) and two grounded capacitors is described. By appropriately connecting the input and output terminals, the proposed circuit can provide lowpass, bandpass, highpass, bandstop and allpass current responses. The filter also offers an independent electronic control...

This paper presents a universal current-controlled current-mode biquad filter employing current controlled current conveyor trans-conductance amplifiers (CCCCTAs). The proposed filter employs only three MOCCCCTAs and two grounded capacitors. The proposed filter can simultaneously realize low pass (LP), band pass (BP), high pass (HP), band reject (BR) and all pass (AP) responses in current form ...

In this work, a first-order low-pass filter is proposed as suitable for time-mode PWM signal processing. processing, the pulse width of rectangular processing variable. The constructed using basic building blocks such time registers and adders so it characterized by low complexity which can lead to modular versatile design higher-order filters. All were designed verified in TSMC 65 nm technolog...
