High Frequency AGC has Digital Control: 05/21/98 EDN-Design Ideas / (added
6/06) Many systems, especially communications, require AGC that functions at 50 MHz. Self-calibrating systems, such as automatic test
equipment, need this high-frequency response but also require digital control of the AGC output voltage. During the calibration cycle, the
test equipment calculates the AGC output voltage necessary to achieve the accuracy requirements and then increments the AGC output voltage
until the system is within specifications. The AGC circuit in Figure 1 uses a DAC to accomplish the digital control, and because the DAC is
the reference input of the AGC circuit, the DAC ultimately sets the AGC output voltage. The HI5731 is a good choice for the DAC, IC3, because
it is inexpensive, has an update rate as high as 100 MHz, and functions with 5V supplies. Also, its output interfaces well with the AGC
circuit.... |

How to generate random numbers: Start with an about 10MHz crystal oscilator,
and a 1000Hz rc oscilator such as a 555 or a few cmos gates. Uses high temperature coefficient capacitors like Z5U's and even thermisters if
you are so inclined for the 1000 Hz oscilator. Run the 10 MHz to a flip flop set up to toggle. Call the
output of this flip flop T1. T1 has close to a 50% duty cycle. Call the 1000Hz output T2.... (circuit design added 10/06) |
