摘要： An integrated circuit includes a first-stage amplifier circuit and a following-stage amplifier circuit connected in series, a common power source pad for supplying power to the amplifier circuits, and metal wires respectively connecting the common power source pad to the amplifier circuits. On the metal wire which connects the first-stage amplifier and the power source pad, an integrator is electrically connected. This arrangement decreases a coupling noise generated in the first-stage amplifier circuit, thereby stabilizing circuit operation of the following-stage amplifier circuit.

摘要： A terrestrial broadcast tuner section is disposed in an area A1, and frequency-converts an externally supplied terrestrial broadcast signal into an IF signal. A terrestrial broadcast analog demodulation section is disposed in an area A3, and demodulates the IF signal frequency-converted by the terrestrial broadcast tuner section. A satellite broadcast tuner section is disposed in an area A2, and frequency-converts an externally supplied satellite broadcast signal into a signal having a frequency band lower than that of the satellite broadcast signal. A digital demodulation section is disposed in an area A4, and demodulates the signal supplied from either one of the terrestrial broadcast tuner section and the satellite broadcast tuner section. With this arrangement, a broadcast receiving apparatus easily changeable from the one for analog and digital broadcasting to the one for digital broadcasting only can be provided.
摘要翻译：地面广播调谐器部分设置在区域A 1中，并将外部提供的地面广播信号频率转换成IF信号。地面广播模拟解调部分设置在区域A 3中，并解调由地面广播调谐器部分频率转换的IF信号。卫星广播调谐器部分设置在区域A 2中，并将外部提供的卫星广播信号频率转换成具有低于卫星广播信号的频带的信号。数字解调部分设置在区域A 4中，并且解调从地面广播调谐器部分和卫星广播调谐器部分中的任一个提供的信号。利用这种布置，可以提供容易地从用于模拟和数字广播的广播接收设备改变为用于数字广播的广播接收设备。
