OP-AMP CONTROLLED SOURCES
BY:• DICIEMBRE, JOHN KEVIN B.
INTRODUCTION:
• Operational amplifiers can be used to form various types of controlled sources. An input voltage can be used to control an output voltage or current, or an input current can be used to control an output voltage or current.
APPLICATION:1. Voltage to Current
Converter2. Current to Voltage
Converter
TYPES OF CONTROLLED SOURCE:1.Voltage - Controlled Voltage Source (VCVS)2.Voltage - Controlled Current Source (VCCS)3.Current - Controlled Voltage Source (CCVS)4.Current - Controlled Current Source (CCCS)
VOLTAGE CONTROLLED VOLTAGE SOURCE (VCVS)
INVERTING OP-AMP NON-INVERTING OP-AMP
