<p>RCA 74,087 In an integrated circuit structure including IF amplifier stages coupled in cascade by d-c blocking capacitors to restrict the noise bandwidth of an FM receiver in which it is employed and receiving power from a common power supply line, separate operating voltage generating circuits are provided for each amplifier stage to inhibit undesired oscillations. Each voltage generating circuit is decoupled from the power supply line by a respective lateral transistor configuration cooperative with a current mirror amplifier arrangement to supply a reference current to the voltage generating circuit.</p> |
