| Abstract: | Firstly, the operation principles of peak holding circuits such as voltage and transconductance typesare introduced. The factors influencing the precision of transconductance peak holding circuit are simulated and an-alyzed by Multisim9. The accuracy holding is greatly influenced by the choosing of peak holding capacitance. Thenthe simplified reference formula for choosing the capacitance values is given. Finally, experiments show that thetransconductance peak holding circuit with MAX436 as design core has higher peak holding accuracy. |
