It's not possible to do same trust between a on-prem AD and AAD. We can set a trust only between two domain or forest on-prem.
In other hand you have others mechanisms you can implemented to let on-prem user access on a Azure resource , like federation and directory synchronization through Azure AD connect
Federate a single AD forest environment to the cloud
