| Abstract: | Discussed are the main structure and features of ispPAC20—a in-system programmable analog circuit, the technique for making voltage controlled oscillators (VCO) based on ispPAC20 and the operation principle of the VCO. The ispPAC20 circuit, without traditional operational amplifiers, external resistors and capacitors, exhibits high performances and high reliability. With ispPAC20, the VCO design and modification become easier. It can be realized by downloading on ispPAC20 the VCO circuit designed by means of PAC-Designer. |
