Single Chip IC with Head Drivers and Pre-Amplifiers for Home VCR

Abstract

The first designing has been made of a fully integrated home VCR IC including head drive amplifiers, Pre-amplifiers and Rec/PB peripheral switches. In order to obtain a good C/N ratio (Carrier to Noise ratio), pre-amp design was optimized by CAD simulation with head and rotary transformer equivalent circuits derived from S parameters measured with a network… (More)
