Mazano Ekuwedzera Kwekuita

Gadzirisa PCB dhizaini yekushanda kwekupisa
Shandisa zvakakodzera bypass capacitors
Funga nezveparasitic mhedzisiro mune yakakwirira-frequency application
Shandisa nzira dzakakodzera dzekuisa pasi

Matambudziko Anowanikwa uye Mhinduro

Symptom	Zvinogona Kukonzera	Solution
Overheating	Kudhirowa ikozvino	Tarisa kusarura, wedzera kupisa sink
Kuwana murombo	Kurerekera kusiri iko	Rongedza bias resistors
Oscillation	Mamiriro ezvinhu	Kuvandudza grounding, wedzera bypassing
