Abstract
A delayed automatic gain control circuit using a simple delayed AGC voltage generation section and capable of fixing a start point of AGC in an RF amplification section at a predetermined received signal level without performing a special adjusting operation even if there are variations in the characteristics of circuit sections. The delayed automatic gain control circuit has a tuner including the RF amplification section, an AGC voltage generation section for generating an AGC voltage dependent on an output signal from the tuner, and an AGC voltage setting section for converting the AGC voltage into a delayed AGC voltage which is supplied to the RF amplification section of the tuner. The AGC voltage setting section is formed by a resistor voltage divider for dividing a power supply voltage and a diode connected to one voltage dividing point of the resistor voltage divider to selectively supply the AGC control voltage to the voltage dividing point according to the level of the AGC voltage. The delayed AGC voltage is output from another voltage dividing point of the resistor voltage divider.
