摘要： PROBLEM TO BE SOLVED: To improve the attenuation of an amplification factor in high pass audible frequencies by decreasing a voltage and connecting this voltage from a middle point obtained by dividing a plate resistance into two through a fixed voltage Zener diode with a screen grid. SOLUTION: In a voltage amplification resistance connecting circuit constituted of a multielectrode electronic tube, a voltage is decreased and connected from a middle point obtained by dividing a plate into two through a fixed voltage Zener diode with a screen grid so that an inner resistance can be decreased without deteriorating the life of a multielectrode electronic tube. In this circuit, the fixed voltage Zener diode voltage is selected so as to be a proper voltage value so that the screen grid voltage can be set so as to be a voltage within the maximum specification. In this circuit, the plate resistance intermediate point voltage is set so as to be 290 V, and the screen grid voltage is set so as to be 86 V when a voltage amplification power supply voltage is 363 V. In this case, the screen grid voltage of a voltage amplification electronic tube WE 310A can be operated with a sufficient margin against the maximum specific voltage 180 V.

摘要： PURPOSE:To reduce the production cost of a single amplifier, to improve its characteristics and to obtain fine reproduced sound from a low frequency band up to a high frequency band by connecting a load to a constant current circuit in parallel equivalently as to AC and allowing the constant current circuit to take charge of a DC component so as to remove the influence of DC upon the load. CONSTITUTION:In order to interrupt DC from a load R (an output transformer or a speaker), a parallel field is constituted by mutually connecting the constant current circuit CRS and the load R in parallel through a capacitor C and allowing the circuit CRS to take charge of a DC component. In order to effectively operate the circuit CRS, the conditions of CRS operation resistance ¦load and CRS operation voltage 2 output voltage of output element should be satisfied and the circuit CRS can be simply assembled from elements such as FETs and beam tubes. Since the DC magnetization of the transformer can be eliminated or the output transformer itself can be omitted, an output drop in a low frequency band can be reduced and a distortion rate also can be reduced.

摘要： Techniques to improve low noise amplifiers (LNAs) with noise canceling are described. LNA includes a first (24) and a second (26) amplifier which work together to noise cancel the noise generated at an input stage circuit (22). The input stage circuit (22) receives an RF signal and is characterized by a first node and a second node. The first amplifier (24) converts a noise voltage at the first node into a first noise current at an output (220) of the first amplifier (24). The second amplifier (26) is directly coupled to the output of the first amplifier and provides noise canceling by summing the first noise current with a second noise current generated by the second amplifier as a function of the noise voltage at the second node. The proposed techniques eliminate the need for large ac coupling capacitors and reduce the die size occupied by the LNA. The elimination of ac coupling capacitors between amplification stages of the LNA allows current reuse resulting in reduced current consumption.
