Patent number: 6665399Abstract: A line driver for connection to a transmission line having a characteristic impedance. The line driver can be arranged in a voltage-mode or a current-mode configuration. In the voltage-mode configuration, the line driver comprises an amplifier, a transformer, a reference resistor and a feedback circuit. The first winding of the transformer has a first end connected to the output of the amplifier and the second winding is connectable to the transmission line. The reference resistor has an end connected to the second end of the first winding at a junction point and the feedback circuit is connected to the input and output of the amplifier and also to the junction point. The reference resistor has a resistance equal to {fraction (1/k)} times the characteristic impedance of the transmission line. The feedback circuit is arranged to produce a voltage at the output of the amplifier substantially equal to −(K−1) times the voltage at the junction point, for a predetermined value of K.Type: GrantFiled: March 25, 1999Date of Patent: December 16, 2003Assignee: Nortel Networks LimitedInventors: Dan Gorcea, Carl Anderson, Gyula Jakab

Patent number: 6137359Abstract: The invention is an amplifier configuration which provides signal gain at very low levels of distortion. The inventive amplifier configuration consists of two amplifiers whose outputs are added to give the total amplified signal. A first amplifier functions in the usual way, amplifying a signal from a voltage source and having a controllable feedback gain. A second amplifier is also fed by the voltage source but applies a feedback gain to the total amplified signal rather than to its own output signal. By selecting the feedback gains to be substantially identical, portions of voltage waveforms that have been removed or altered due to clipping or other forms of distortion are restored by the second amplifier. The invention is particularly useful when amplifier gain is low, e.g., at high frequencies. Suitable implementations are in the voltage domain, using operational amplifiers, or in the current domain, using, for example, voltage-controlled current sources.Type: GrantFiled: December 7, 1999Date of Patent: October 24, 2000Assignee: Nortel Networks CorporationInventors: Dan Gorcea, Robert M.

Patent number: 6107884Abstract: The invention is an improvement to an amplifier configuration employing an amplification stage (e.g., an operational amplifier) biased via biasing terminals and a follower stage (e.g., an emitter-follower BJT pair), the follower stage being capable of producing the same voltage as the amplification stage but at a higher current. The improvement consists of feeding a fraction of the output voltage of the follower stage to the biasing terminals of the amplification stage. Specifically, the output of the follower stage is connected to the biasing terminals via a common bootstrap resistor and respective capacitors. The capacitors behave as a DC block and as an AC short-circuit. The biasing terminals are then connected to respective biasing resistors which could then be connected to respective supply voltage sources. In this way, the maximum permitted amplitude of the output voltage is increased, leading to less distortion and less frequent saturation of transistors in the amplification stage.Type: GrantFiled: November 27, 1998Date of Patent: August 22, 2000Assignee: Nortel Networks CorporationInventor: Dan Gorcea
