A transconductance amplifier and method for improving the phase response and linearity. A differential amplifier circuit receives differential signals for amplification on respective bases of input bipolar transistors. The transistors amplify a small signal received on the based connections to produce an amplified output current. The differential amplifier circuit is connected to load impedances which form a cascode transconductance amplifier output stage. Feedback transistors provide a feedback voltage from the emitters of each of the different bipolar transistors to the base, improving the linearity of the differential amplifier. Phase compensation is provided by cross coupling through first and second capacitors a portion of each individual differential signal component to the base connections of the differential amplifier input transistor.       Recently Added Patents Tear resistant bag Cleaning sheet Method and system for direct contact of hot liquor with wood chips in transfer circulation Portable computer Device for electrochemical water preparation Mechanical resonating structures and methods Magnetic memory devices including magnetic layers separated by tunnel barriers   Randomly Featured Patents Fast transmission gate switch Cross faucet handle Semiconductor light emitting device and method of manufacturing the same Apparatus and method for dispensing vapocoolants Method for integrated desulfurizing of pig iron melt and steel melt Fluid inlet device, use, and method of retrofitting Near real-time multi-party task authorization access control System and method for control of aeroelasticity effects Surfactant compositions useful in enhanced oil recovery processes Elevator with separated speed governor and position detector © 2006-2008 PatentGenius.
