    摘要: A receiver (400) includes a tracking bandpass filter (420) and a signal processing circuit (430-480). The tracking bandpass filter (420) has a first input for receiving a radio frequency (RF) signal, and an output, and includes a first portion (731) on a semiconductor die (730), and at least one inductor (721). The at least one inductor (721) is operatively coupled to the first portion of the tracking bandpass filter (420). The signal processing circuit (430-480) has an input coupled to the output of the tracking bandpass filter (420), and an output for providing a processed signal. The semiconductor die (730) and the at least one inductor (721) are integrated into a single multi-chip module (MCM) (710).

    摘要: An integrated wideband receiver includes first and second signal processing paths and a controller. The first signal processing path has an input, and an output for providing a first processed signal, and comprises a first tracking bandpass filter having a first integrated inductor. The second signal processing path has an input, and an output for providing a second processed signal, and comprises a second tracking bandpass filter having a second integrated inductor. The controller is for enabling one of the first and second signal processing paths corresponding to a selected channel of a radio frequency (RF) input signal to provide an output signal. The controller, the first integrated inductor, and said second integrated inductor are formed on a single integrated circuit chip.

    摘要: Systems and methods are disclosed for automatic gain control (AGC) for analog television signals using feed-forward signal path delay. Adjustments to the AGC frequency response are achieved by introducing an intentional delay in the signal path of sufficient length to allow time for measurement of a horizontal sync pulse level and for application of a feed-forward amplitude correction based upon this measurement to the same horizontal line.
