Abstract-A gigahertz analog multiplier based on OTA and squaring is proposed. The multiplier has gigahertz frequency response is suitable to use in communication system. The circuit is based on 0.18 µm CMOS technology simulated using PSPICE level 7. This technique provides; wide dynamic range, GHz-bandwidth response and low power consumption. The proposed circuit has been simulated with PSPICE and achieved -3dB bandwidth of 3.96GHz. The total power dissipation is 0.588mW with ±1V power supply voltages..
This paper presents a new current-mode universal filter with three inputs and three outputs employing only two multiple-output current-controlled current conveyors and two grounded capacitors. The proposed circuit can simultaneously realize of lowpass, bandpass, highpass and bandstop current responses from same configuration. The proposed filter also enjoys an independent current control of parameters natural angular frequency and quality factor through adjusting the bias currents of the translinear current conveyors. The proposed configuration no requires of any cancellation constrain for realizing all the filter responses. The characteristics of the proposed circuit are simulated using PSPICE to confirm the theory.
In this paper, analysis results of an FPGA (Field-Programmable Gate Array) designed in RTL (Register Transfer Level) shows that does not have a problem in routing. It has many advantages than conventional FPGA developed by the transistor level. However, the crossbar switch of the FPGA designed in RTL has a problem with the direction of the signal. The direction is fixed in one direction unlike the conventional crossbar switch. Routing is analyzed by using the circuit of three input two output.
