Din cate stiu eu nu se prea fac condensatoare peste 100-150 pF pe siliciu din motive economice. Cele mai scumpe componente intr-un integrat sunt rezistentele de valori mari (peste 10K) la fel si condensatoarele(peste 100pF). Rezistentele ocupa un spatiu foarte mare in comparatie cu tranzistoarele si sunt si foarte proaste (tolerante mari, variatii mari cu temperatura etc.). Cam la fel este si cu condensatoarele.
