10 kHz VFC uses Charge Pump Variation: 04/09/98 EDN-Design Ideas
DPP Adds Versatility to VFC: 11/14/02 EDN-Design Ideas /
The basic VFC (voltage-to-frequency converter) comprises an
integrator (IC1) and a Schmitt-trigger circuit (IC2). The
integrator converts the dc input voltage, VIN, to a linear
voltage ramp, and the Schmitt trigger sets the limits of the
integrators output voltage.
LowSide CurrentSensing Circuit Uses Synchronous VToF Converter
: 09/02/02 Electronic Design - Ideas for Design / A
voltage-to-frequency converter (VFC) can easily measure current
flow and convert it to a digital signal understood by the
timer/counter input of a microcomputer (?C) or microprocessor.

08/19/02 Electronic Design - Ideas for Design /
Personal-computer sound cards are sometimes used for analog
audio signal acquisition. Also, the Web features many free
programs that implement virtual tw1o-channel oscilloscopes by
acquiring signals through the sound card. However, sound cards
