OPERATIONAL TRANSCONDUCTANCE AMPLIFIERS FOR GIGAHERTZ APPLICATIONS You Zheng
... A novel CMOS operational transconductance amplifier (OTA) is proposed and demonstrated in this thesis. Due to its feedforward-regulated cascode topology, it breaks the previous OTA frequency limit of several hundred MHz and operates at frequencies up to 10 GHz with a large transconductance. This is ...

Studies on Tuning of Integrated Wave Active Filters Johan Borg LiTH-ISY-EX-3401-2003
... The phase of the output signal from the filter is compared with that of the reference-signal. The phase comparison is carried out by multiplying the signals, as the DC-component of the product of two signals with the same frequency will depend on the phase difference. If there is a 90 degree phase d ...

Bode plot
In electrical engineering and control theory, a Bode plot /ˈboʊdi/ is a graph of the frequency response of a system. It is usually a combination of a Bode magnitude plot, expressing the magnitude of the frequency response, and a Bode phase plot, expressing the phase shift. Both quantities are plotted against a horizontal axis proportional to the logarithm of frequency.
