Manufacturer:ATMEL Description:Operation is similar to a conventional charge-balance VFC. An input operational amplifier (Figure 1) is configured as an integrator so that a positive input voltage causes an input current to flow in CINT. This forces the integrator output to ramp negatively. When the output of the integrator crosses the reference voltage (5V), the comparator trips, activating the clocked logic circuit. Once activated, the clocked logic awaits a falling edge of the clock input, followed by a rising edge. On the rising edge, switch SW1 is closed for one complete clock cycle, causing the reset current, I1, to switch to the integrator input. Since I1 is larger than the input current, IIN, the output of the integrator ramps positively during the one clock cycle reset period. The clocked logic circuitry also generates a VFC output pulse during the reset period. |
